How many atoms of each element does calcium sulfate, caso4, contain?

Calcium = 1, Sulfur = 1, Oxygen = 4

Explanation:

When the element does not have a subscript next to it, that means there is only one atom. Oxygen, or O, has a subscript of 4 so there are four atoms. Hope this helped ⋆^‿^⋆

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
