# What are the subatomic particles?

To a first, and useful approximation, atoms are made up of (i) $\text{electrons}$, charged particles with negligible mass, the which are conceived to whizz about a massive nuclear core, consisting of (ii) $\text{protons}$, massive particles with AN OPPOSITE ELECTRONIC CHARGE to the electron (and therefore atoms are to a first approx. electrically neutral), and (iii) $\text{neutrons}$, massive particles with ZERO ELECTRONIC CHARGE.
