How many atoms are present in PO43- ion?

Answer 1

PO4-3 is an ion, and therefore does not have molecules. In a formula unit, there are 5 atoms consisting of one phosphorus and four oxygen atoms. This can always be found from a proper formula by summing all the subscripts immediately following atomic symbols, multiplied if appropriate for any particular element by the subscript immediately following a right parenthesis between which and a left parenthesis an element symbol appears. For example, the formula unit Fe3(PO4)2 contains 3 iron atoms, 2 phosphorus atoms and 8 oxygen atoms, because the phosphorus and oxygen symbols are between parentheses followed by a subscript and the iron symbol is not.

Answer 2

4 is subscript den,

5:phosphorous-1, oxygen-4

i dunno if ts rite or not!!

Answer 3

P - 15 protons

O4 - 32 protons

47 protons total, and 50 electrons to make it 3-

Answer 4

There are 10 atoms present in the PO4^3- ion: 1 phosphorus atom and 4 oxygen atoms in the phosphate group, along with 3 additional oxygen atoms due to the charge of -3 on the ion.
