Sulfate (SO4) has an electrovalency of -2
As magnesium sulfate is an ionic compound, it creates an ionic lattice. Therefore it doesn't exist as seperate molecules.
Zinc has two valence electrons.
Aluminum has 3 valence electrons.
3 valence electrons
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.
As magnesium sulfate is an ionic compound, it creates an ionic lattice. Therefore it doesn't exist as seperate molecules.
There are 32 valence electrons in the Lewis structure of the sulfate ion (SO3^2-), which consists of one sulfur atom and three oxygen atoms. Sulfur contributes 6 valence electrons, and each oxygen contributes 6 valence electrons, totaling 32 valence electrons in total.
There are 32 electrons available for bonding in the sulfate ion (SO4^2-). Each oxygen contributes 6 valence electrons, and the sulfur contributes 6 valence electrons, giving a total of 32 electrons.
