Question

The number of neutrons in the radioactive isotope of carbon is _______.

Answer 1

Isotope: Isotopes of an atom have the same atomic number but different atomic masses. The number of neutrons differs.

• For example, the isotope of carbon is C-14.

In carbon-12,

• No. of protons = 6
• No. of neutrons = 6

In carbon-14,

• No. of protons = 6
• No. of neutrons = 8.

The number of neutrons in the radioactive isotope of carbon is 8.
