Question

The commonest form of the Carbon atom that exists is at times referred to as C12. An isotope of this atom is called C14. C14 must have a different number of _____ than C12.

Answer 1

mass number

Step-by-step explanation:

bc it just is

Answer 2

neutrons

Step-by-step explanation:

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

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

Thus both C14 and C12 have same number of protons as they have same atomic number.

The difference in the mass number of both the isotopes is sue to the difference in the number of neutrons.

Atomic number = Number of protons = 6

For CC- 14, Number of neutrons = 14 - 6 = 8

For C 12, Number of neutrons = 12 - 6 = 6
