Find the number of protons, neutrons, and electrons for carbon-12, carbon-13, and carbon-14 respectively.

A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).

Carbon-13 (13C) is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons and six electrons.

Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons).

Hope this helps! =D

yes it is balanced
