Ions with Lewis Dot structures

First things first! .. .. Na. .Cl: Na [ ] :Cl: .. .. 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. 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: Na [ ] :Cl: .. ..

It has an extra electron For Polyatomic Ions… The polyatomic ion is a covalently bonded structure with an ionic bond to another substance. NH4F H . F H-N-H . H That goes to Fluoride It has an extra electron
