Answer:
The atomic number of nitrogen is 7. The number of electrons a neutral nitrogen atom has is 7 , and its atomic mass is approximately 14 amu.
Step-by-step explanation:
Nitrogen has an atomic number of 7 which means the number of proton is 7. The electron number of a neutral atom of Nitrogen is 7 because it has not gone into any reaction to gain electron . The charge of Nitrogen is usually 3- as it requires 3 electron to attain the octet rule.
The number of electron in a neutral charge of an atom is usually equal to the proton number. The electron are usually shared(covalent) when it goes into bonding with other atoms.
The atomic mass of an element is approximately the sum of the number of proton and neutron of an atom. The atomic mass of Nitrogen is approximately 14.
