Question

The number of neutrons present in carbon-14 are _______.

• A. 6
• B. 14
• C. 12
• D. 8

Answer 1

The correct option is D 8

Carbon-14 is an isotope of carbon. Isotopes of an element have same number of protons but different number of neutrons.
Atomic number of carbon is 6.
So, the number of protons = 6.
Atomic mass number for carbon-14 is 14.
Mass number = Number of protons + Number of neutrons
Therefore,
Number of neutrons = Mass number - Number of protons
=14-6 = 8
Thus, it has 8 neutrons and 6 protons.
