Chemistry Ionic Naming

When naming ionic compounds with transition metals you need to include roman numerals to show the _____ of the metal..

• atomic number

• mass number

• charge

• ionization energy

If I gain electrons I become

• Positive because I've added to my atom

• negative because I've added electrons

• same because i'm balanced

• equal because now I have electrons
