Problem: Give the charges of the cation in each of the following compounds CaO, Na2SO4, KClO4, Fe (NO3) 2, Cr (OH) 3.

FREE Expert Solution

a. CaO

O → group 6A → -2 charge

Ca → group 2A → +2 charge


b. Na2SO4

SO42- → polyatomic ion → -2 charge

Na → group 1A → +1 charge


c. KClO4

K → group 1A → +1 charge

ClO4- → polyatomic ion → -1 charge
