   3. Ions

      Anotações:

      • When atoms lose or gain electrons they form positive or negative ions

Anotações:

• 1 or more of the same type of atom 

1. Compound
   1. Ionic Bonding

      Anotações:

      • Metal loses an electron to form a positive metal ion. Non metal gains elctron lost by metal to form a negative ion compound

Anotações:

• How many protons are in the nucleas

Anotações:

• How many protons and electrons are in the atom

Anotações:

• Groups in the periodic table show how many electrons are in the outside shell of the atom of that specific element in that group
• All elements in one group have got similar properties
