Each row on the Periodic Table is called a (a)   Each row represents the number of ​ (b)  

• Period
• Energy Levels
• Group
• Valence electrons

Why are ions formed?

• To make our lives difficult

• Because atoms want to be stable with 8 valence electrons

• Because atoms have the same number of protons and electrons

• Because atoms gained neutrons
