How many electrons are in a neutral lithium atom?

Answer 1

An element's charge experiences major contributions from protons and electrons, which effectively have charges of #+1# and #-1#, respectively.

Protons and electrons must be equal in neutral elements because an imbalance would not result in the cancellation of all charges.

Lithium has an atomic number #Z# of #3#, so by definition, it has #3# protons.

Hence, neutral lithium atoms must contain #3# electrons.
