Question

Write formulas for the following compounds containing complex anions.

rubidium hyponitrite
magnesium bromite

Answer 1

Use the table I gave you below for the formula of the anion, add it to the metal. For example,
the second one is Mg(BrO2)2. It takes two BrO2 anions with a valence of -1 to equal Mg with a valence of 2.
