1. Ions with Lewis Dot structures

2. First things first! Determine whether the bond will be ionic or covalent! Determine whether the bond will be ionic or covalent! A nonmetal and a metal is ionic if they are both nonmetals it is covalent, hydrogen is not a metal. A nonmetal and a metal is ionic if they are both nonmetals it is covalent, hydrogen is not a metal. To draw an ionic bond remove the electron(s) from the cation and add them to the anion. Show the charges on each ion. To draw an ionic bond remove the electron(s) from the cation and add them to the anion. Show the charges on each ion. Na..Cl:.. :Cl:.. - Na + [ ]

3. For Polyatomic Ions… The polyatomic ion is a covalently bonded structure with an ionic bond to another substance. The polyatomic ion is a covalently bonded structure with an ionic bond to another substance. NH 4 F NH 4 F H-N-H H H. It has an extra electron F. That goes to Fluoride

4. For Polyatomic Ions… The polyatomic ion is a covalently bonded structure with an ionic bond to another substance. The polyatomic ion is a covalently bonded structure with an ionic bond to another substance. NH 4 F NH 4 F H-N-H H H It has an extra electron F That goes to Fluoride - +
