Which of the following is the correct isotope notation for the element above?
a.
b.
c.
d. user: how many neutrons are in an atom of carbon with a mass number of 14?
a. 6
b. 7
c. 8
d. 14

The number of neutrons in an atom of carbon are 8

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
