Why are neutrons always more than protons in an atom?

Answer 1

Is that really true?

Helium has 2 protons and 2 neutrons.

Carbon-12 has 6 protons and 6 neutrons.

Nitrogen-14 has 7 protons and 7 neutrons

So, even though there are usually more neutrons than protons, it isn't always the case. Now, why is it that atoms usually have more neutrons than protons (especially in the heavier elements).

Protons are positively charged particles and thus repel each other in the nucleus. With heavier elements especially, these repulsive forces become much greater. So one can look at the neutrons (neutral particles) as sort of a buffer to get in the way of the protons to reduce their repulsion and thus increase the stability of the nucleus.
