Answer 1

Answer #1

Atoms have protons, electrons and neutrons whereas neutrons are neutral or no charge on it, only electrons and protons have charge on them.

Each neutral atom has equal number of protons and electrons and there is no charge on it therefore we can say that protons and electrons have equal magnitude of charge.
