In the Bohr model, a nitrogen atom has a central nucleus, composed of seven protons and seven neutrons, surrounded by seven electrons. Two of the electrons are in the first energy level while the other five are in the second energy level.
Furthermore, is nitrogen an atom or a molecule?
Nitrogen itself is an element. But nitrogen is found as N2 in nature. A compound is a molecule that contains at least two different elements (i.e. water) while a molecule is formed when two or more atoms join chemically. All compounds are molecules but not all molecules are compounds.
What is nitrogen made up of?
Nitrogen is an element that can combine with itself or with other elements to make different compounds. For instance nitrogen gas, N2, is a compound made when two nitrogen atoms form a chemical bond. It makes up about 80% of the atmosphere, while oxygen gas, O2, makes up a little less than 20% of the atmosphere.
Is it n2 or N?
N2 is the formula of the nitrogen molecule, which has two atoms of nitrogen in it.. The nitrogen gas exists only as N2 molecules in free state.
