Aldo Joseph · Answer 2

A) 6

Explanation:

The number of protons is the defining characteristic of an element. This means that a carbon atom has always 6 protons.

Isotopes are atoms of the same element, equal number of protons, and different number of neutrons.

The carbon-12 atom has 6 protons and 6 neutrons.

The carbon-14 atom has 6 protons and 8 neutrons.
