Does nitrogen gas consist of a molecule of two nitrogen atoms?
Yes. Nitrogen gas has the formula N2. A molecule of nitrogen gas consists of two atoms of nitrogen covalently bonded.
Nitrogen pairs up, into the N2 molecule which has a very strong triple bond. There is relatively little attraction between one nitrogen molecule and another, so they move independently and form a gas. In phosphorus, the atoms do not pair up, they bond to their neighboring atoms, thus forming a network of bonding that holds the atoms together into a solid.
6.226 x 10^28 atoms of Nitrogen approximately mole = 6.226 X 10^28 objects Nitrogen exists as a diatomic molecule, so in 0.5 moles of diatomic nitrogen gas there are exactly 1 moles worth of molecules, therefore the number of atoms in 0.5 moles of nitrogen gas is equal to the value of the mole which is approximately 6.226 x 10 ^ 28 atoms
Nitrogen the gas which is about 3/4 of the atmosphere consists of molecules. Each of these molecules consists of two atoms of nitrogen that are chemically bonded together. We don't refer to nitrogen gas as a compound because, by definition, a compound must be two or more different elements chemically bonded together.
The reason why nitrogen gas is inert at room temperature is because the triple bond between the two nitrogen atoms in each nitrogen molecule (N2) is very strong, and therefore it takes a lot of energy to break that bond, and until that bond is broken, the nitrogen cannot react with any other chemical.
Molecules. A common molecule in air is O2, or two oxygen atoms stuck together. A 'particle' is a general term for anything very, very small. A molecule specifically indicates a combination of two of more atoms. Atoms are the smallest things which can exist independently, they come in over 100 different types and all substances are made up of different combinations of atoms. For example iron is made up of Iron atoms but steel is…
