Unit 6: Periodic Table and Bonding - Mark Rosengarten

H) Naming Ions
1) Name the following ions. Check the Periodic Table to see if you need to use the Stock System for any of
them.
Ion Name Ion Name Ion Name Ion Name

C -4 Br -1 F -1 I -1
2) Using Reference Table S, determine which atom in each pair has the higher electronegativity and ionization
energy
Compare Higher EN Higher IE Compare Higher EN Higher IE
N or O
