Front

What does it mean if an element is in period 3 on the Periodic Table?

Back

It has 3 energy levels/shells in its electron cloud.

Front

What is the maximum number of electrons in the third energy level?

Back

18

Front

What is the significance of the Periodic Table's groups?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.

Front

What is the atomic number of an element?

Back

The number of protons in the nucleus of an atom.
