Answer: The number of neutrons in an atom of carbon are 8

Step-by-step explanation:

Atomic number is defined as the number of electrons or number of protons present in a neutral atom. It is represented by Z.

Z = Atomic number = Number of protons = Number of electrons

Mass number is defined as the sum of number of protons and number of neutrons present in an atom. It is represented as A.

A = Mass number = Number of neutrons + Number of protons

We are given:

Atomic number of Carbon = 6 = Number of protons

Mass number = 14

Number of neutrons = Mass number - Atomic number = 14 - 6 = 8

Hence, the number of neutrons in an atom of carbon are 8
