Consider a neutral atom with 30 protons and 34 neutrons. What is the atoms number of electrons?
All you needed to know was that:
- The atom is neutral.
- The atom has

Protons are positively charged, and electrons are negatively charged.
Therefore, a neutral atom has the same number of protons as electrons, no matter the number of neutrons.
You have two charges, and two types of particles. If
