Ions and Ionic Charge

When atoms lose or gain electrons, they become charged particles called ions. The position of an element in the periodic table can often help predict its ionic charge, since elements in the same group tend to form ions with similar charges.

Finding Ionic Charge

Finding ionic charge using the Periodic Table is an essential skill in chemistry.

Valence Electrons and Ionic Charge

Valence electrons and ionic charge are related since both involve electrons in the outer shell of an atom.
