Covalent bonds Ionic bonds
Covalent Bonds
Happen when atoms share electrons
Covalent Bonds
Happen when atoms share electrons Molecules have exact proportions of elements
Covalent Bonds
Happen when atoms share electrons Molecules have exact proportions of elements Example: water
Covalent Bonds

Ionic Bonds
Happen when atoms transfer electrons
Ionic Bonds
Happen when atoms transfer electrons Ions stick together because of electric charge
Ionic Bonds
Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt
