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.
In the compound Al₂O₃, there are two aluminum (Al) atoms and three oxygen (O) atoms. Aluminum has 3 valence electrons, so 2 Al atoms contribute a total of 6 valence electrons. Oxygen has 6 valence electrons, so 3 O atoms contribute 18 valence electrons. Therefore, the total number of valence electrons in Al₂O₃ is 6 + 18 = 24 valence electrons.
Zinc has two valence electrons.
Aluminum has 3 valence electrons.
3 valence electrons
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.
