Detrek Browning Stayed True To Fmu And Became The Schools All
In an early January game against Clayton State, Detrek Browning waited calmly behind the three-point line while teammate Brandon Parker battled for a loose ball in the lane. Eventually, Parker swatted the ball towards Browning, who gathered it in, paused to set himself and casually flipped in a three-pointer that etched his name into a prominent place in the FMU record books. With that relatively unremarkable basket, Browning became something quite remarkable the leading career scorer in the schools almost 50-year-old history.
That the record-setter came on a routine play is not surprising. Brownings calling card as a player is his ability to score, seemingly without effort to make a unique ability to find ways to put ball basket appear quite ordinary.
What was remarkable about the play is that Browning was around to do it at all.
FMU Basketball standout Detrek Browning
The dynamics of college basketball at all levels have changed dramatically in the past decade. Players move regularly and easily from school to school, looking for the next bit of slightly greener grass and there is not much hard-working coaches and schools can do about it. Their path is fraught with peril.
After he averaged 20.1 points a game for FMU in 2015-16, officially his sophomore season, word got around to Browning. There were schools out there Division I schools who were interested. And Browning knew the drill. Friends, foes, even some of his teammates, had gone that route.
Faraday Unit Of Charge
Related to Faraday’s constant is the “faraday”, a unit of electrical charge. It is much less common than the coulomb, but sometimes used in electrochemistry. One faraday of charge is the magnitude of the charge of one mole of electrons, i.e. 96485.33212… C.
Expressed in faradays, the Faraday constant F equals “1 faraday of charge per mole”.

Physical And Chemical Properties
At room temperature fluorine is a faintly yellow gas with an irritating odour. Inhalation of the gas is dangerous. Upon cooling fluorine becomes a yellow liquid. There is only one stable isotope of the element, fluorine-19.
Because fluorine is the most electronegative of the elements, atomic groupings rich in fluorine are often negatively charged. Methyl iodide and trifluoroiodomethane have different charge distributions as shown in the following formulas, in which the Greek symbol indicates a partial charge:
The first ionization energy of fluorine is very high , giving a standard heat formation for the F+ cation of 420 kilocalories per mole.
The high oxidizing power of fluorine allows the element to produce the highest oxidation numbers possible in other elements, and many high oxidation state fluorides of elements are known for which there are no other corresponding halidese.g., silver difluoride , cobalt trifluoride , rhenium heptafluoride , bromine pentafluoride , and iodine heptafluoride .

Chemistry Is A Physical Science
Chemistry is typically considered a physical science, as defined by the Encyclopedia Britannica, because the study of chemistry does not involve living things. Most of the chemistry involved in research and development, such as making new products and materials for customers, falls within this purview.
But the distinction as a physical science becomes a bit blurry in the case of biochemistry, which explores the chemistry of living things, according to the Biochemical Society. The chemicals and chemical processes studied by biochemists are not technically considered “living,” but understanding them is important to understanding how life works.
Key Takeaways: What Is Fluoride
- Fluoride is the name given to the negatively-charged ion of the fluorine atom .
- A fluoride may also be the name of a compound that contains the element.
- Fluoride is found in toothpaste and public water supplies in some countries. Other countries view fluoride as a toxic compound and seek to remove it from their water.
Fluoride is the negative ion of the element fluorine. The symbol for the element fluorine is F. Fluoride often is written as F-, which stands for the anion of fluorine that has a -1 electrical charge. Any compound, whether it is organic or inorganic, that contains the fluoride ion is also known as a fluoride. Examples include CaF2 and NaF . Ions containing the fluoride ion are similarly called fluorides .
To summarize: fluorine is an element fluoride is an ion or a compound which contains the fluoride ion.
Fluorides are found in toothpaste and added to public drinking water in some countries. Water fluoridation usually is accomplished by adding sodium fluoride , fluorosilicic acid , or sodium fluorosilicate to drinking water.

Industrial Routes To F2
Moissan’s method is used to produce industrial quantities of fluorine, via the electrolysis of a potassium fluoride/hydrogen fluoride mixture: hydrogen and fluoride ions are reduced and oxidized at a steel container cathode and a carbon block anode, under 812 volts, to generate hydrogen and fluorine gas respectively. Temperatures are elevated, KF2HF melting at 70 °C and being electrolyzed at 70130 °C . KF, which acts to provide electrical conductivity, is essential since pure HF cannot be electrolyzed because it is virtually non-conductive. Fluorine can be stored in steel cylinders that have passivated interiors, at temperatures below 200 °C otherwise nickel can be used. Regulator valves and pipework are made of nickel, the latter possibly using Monel instead. Frequent passivation, along with the strict exclusion of water and greases, must be undertaken. In the laboratory, glassware may carry fluorine gas under low pressure and anhydrous conditions some sources instead recommend nickel-Monel-PTFE systems.
The Five Main Branches Of Chemistry
Traditionally, chemistry is broken into five main branches, according to the online chemistry textbook published by LibreText. There are also more specialized fields, such as food chemistry, environmental chemistry and nuclear chemistry, but this section focuses on chemistry’s five major subdisciplines.
Analytical chemistry involves the analysis of chemicals, and includes qualitative methods like looking at color changes, as well as quantitative methods like examining the exact wavelength of light that a chemical absorbed to result in that color change.
These methods enable scientists to characterize many different properties of chemicals, and can benefit society in a number of ways. For example, analytical chemistry helps food companies make tastier frozen dinners by detecting how chemicals in food change when they are frozen over time. Analytical chemistry is also used to monitor the health of the environment by measuring chemicals in water or soil, for example.
Biochemistry, as mentioned above, uses chemistry techniques to understand how biological systems work at a chemical level. Thanks to biochemistry, researchers have been able to map out the human genome, understand what different proteins do in the body and develop cures for many diseases.
Inorganic chemistry is used to create a variety of products, including paints, fertilizers and sunscreens.

Does The Element Have Any Toxic Hazards
Prolonged exposure to the skin and eyes can cause burns and irritation. When accidentally inhaled, it can affect the lungs. Repeated exposure may have severe health effects like diarrhea, constipation, nosebleeds, and kidney and liver damage .
- It is one of the few elements to form a layer on diamonds .
- F is the most reactive and electronegative of all elements .
What Do Chemists Do
Chemists work in a variety of fields, including research and development, quality control, manufacturing, environmental protection, consulting and law. They can work at universities, for the government or in private industry, according to the ACS.
Here are some examples of what chemists do:
Research and development
In academia, chemists performing research aim to further knowledge about a particular topic, and may not necessarily have a specific application in mind. Their results, however, can still be applied to relevant products and applications.
In industry, chemists in research and development use scientific knowledge to develop or improve a specific product or process. For example, food chemists improve the quality, safety, storage and taste of food pharmaceutical chemists develop and analyze the quality of drugs and other medical formulations and agricultural chemists develop fertilizers, insecticides and herbicides necessary for large-scale crop production.
Sometimes, research and development may not involve bettering the product itself, but rather the manufacturing process involved in making that product. Chemical engineers and process engineers devise new ways to make the manufacturing of their products easier and more cost effective, such as increasing the speed and/or yield of a product for a given budget.

What Is Spdf Configuration
Recently in my chemistry classes, the teacher spoke about SPDF configuration and then said that we’ll be taught about it in higher classes.
But I’m sorta curious to know that what is SPDF configuration and is there something like – obtaining electronic configuration in SPDF format?
- 11$\begingroup$Sounds like your teacher was talking about the electron configuration, though, I’ve never heard anyone calling it “SPDF configuration”.$\endgroup$May 10 ’15 at 17:46
- 2$\begingroup$Without knowing the context , this could relate to term symbols.$\endgroup$
s, p, d, f and so on are the names given to the orbitals that hold the electrons in atoms. These orbitals have different shapes and energies .
So for example,
- a hydrogen atom with one electron would be denoted as $\ce$ – it has one electron in its 1s orbital
- a lithium atom with 3 electrons would be $\ce$
- fluorine has 9 electrons which would be $\ce$
Again, as we read from left to right the energy of the orbital increases and the superscript shows the number of electrons in the orbital. You can read more here.

What Is The Formula Of The Compound Formed By Ba And F
is the chemical symbol for the metal barium, and #”F”# is the chemical symbol for the nonmetal fluorine. The name of this compound is barium fluoride. Usually metals and nonmetals form ionic compounds when chemically combined.
Since this is an ionic compound, its chemical formula is called a formula unit because there are no discrete molecules. A formula unit represents the lowest whole number ratio of elements in the compound.
Barium is a group 2 element. Group 2 elements form cations with a #2^+# charge. The formula for the barium ion is #”Ba”^”# . Fluorine is a group 17 element. Group 17 elements form anions with a #1^-# charge. The formula for the fluoride ion is #”F”^”# .
Ionic compounds are neutral, so the charges of the positive and negative ions must equal zero when added. So for every #”Ba”^”#
