4. Calculate the percent of the elements that are in bold in the following chemical formulas: a. Cu3”P”2
b. (“N”H4)2SO3
I PUT THE BOLD ELEMENTS IN QUOTATIONS

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
