The number of fundamental particles in an atom of the lightest isotope of carbon are
Correct answer: B. 12
- A. 6
- B. 12
- C. 20
- D. 18
Explanation
The lightest isotope of carbon is Carbon-12, which consists of 6 protons and 6 neutrons. Therefore, the total number of fundamental particles in an atom of Carbon-12 is 6 protons + 6 neutrons = 12.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
