Why is it so important to specify the charge of a transition metal?

• Because you have to for any metal

• Because transition metals can make ions of different charges

• Because transition metals start with one charge and end with another, so you have to write both charges

• None of these are correct.

Why do transition metals get different rules for their names and formulas?

• atoms are larger

• cations have many different charges

• they have more protons

• they are rare elements
