Theatomic numberof fluorine is nine, and the element belongs to the halogen group. It is the lightest of the halogen gases, and the most reactive naturally occurring element, due to its electronegative configuration. On the periodic table of elements, fluorine is identified with the symbol F. ...
Fluorine is a naturally occurring gas that is quite irritating to the eyes, skin, and respiratory system. When it is combined with sodium, however, it's easily dissolvable in water, making it an ideal way to add fluorides to drinking water, toothpaste, mouthwashes, and a variety of other...
What is the chemical formula for fluorine gas? What element is named after a female scientist? In carbon dioxide what element is combined with carbon? What is a chemical symbol in science? What chemical element is naturally green? What form of energy provides power for a gas stove?
fluorine, bromine, and hydrogen (the halogen family in the periodic table of the elements). These are often described by the general termhalocarbons.The compounds include chlorofluorocarbons (CFCs which are used as refrigerants, foam-blowing agents, electronics cleaners, and industrial solvents) as we...
It is the phase that is the least dense as it is mostly comprised of empty space between the gas molecules. Gases can be ''invisible'', such as the air we breathe, or visible, such as iodine or bromine gas. We are surrounded by gases, and two are very important to our lives in ...
A naturally occurring substance made up of the element fluorine, found naturally in rocks, plants, water, and soil. Water absorbs fluoride from the ground as it passes through. However, the amount of fluoride may differ from one place to another. If you are consuming well water, it is impo...
One method involves changing the common molecular structure of CFCs "by sticking a disruptive hydrogen atom into the stable arrangement of chlorine and fluorine. Because these new molecules are less stable, they break up in the lower atmosphere and a re less liable to reach the stratosphere where...
The scientific study of matter's characteristics and behaviour is known as chemistry.Chemistry vocabularyandChemistry glossaryare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up...
chlorine- a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water)
a wide range of microorganisms called diazotrophs, including bacteria such as azotobacter, and archaea, naturally conduct nitrogen fixation in the soil. some nitrogen-fixing bacteria, particularly legumes, have symbiotic relationships with certain plant groups. q4 what would happen if nitrogen-fixing ...
