Sulfate (SO4) has an electrovalency of -2
30
As magnesium sulfate is an ionic compound, it creates an ionic lattice. Therefore it doesn't exist as seperate molecules.
H2O2 is a compound, and the concept of "valence electrons" applies to atoms but not to compounds. If the question is or should be intended to be, "How many valence electrons did the atoms in one formula unit of H2O2 have before they reacted to form the compound?", the answer is one from each hydrogen atoms and six from each oxygen atom, for a total of 14.
6 valence electrons
how many valence electrons does family 1 have
8 valence electrons
