Answer: The number of neutrons in nitrogen atom is 7
Step-by-step explanation:
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
We are given:
Atomic number = 7
Mass number = 14
Number of neutrons = Mass number - atomic number = 14 - 7 = 7
Hence, the number of neutrons in nitrogen atom is 7
