Phosphate (PO4-3) has five valence electrons from phosphorus and six per oxygen atom for a total of 29.
32
PO^4-3
Phosphate has 5 valence electrons
Oxygen has 6(4)=5+24=29+3=32
and then you just add three more valence electrons to get a grand total of 32.
A phosphide ion has 8 valence electrons.
Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
Hydrogen has 1 valence electron, phosphorus has 5 valence electrons, and oxygen has 6 valence electrons. So, if you totaled all of the valence electrons in the ion HPO42- you'd get 1 + 5 + 6 X 4 + 2 = 32. However, you should realize that the term "valence electron" really only applies to individual atoms, not compounds. The only electrons one would concern themselves with in the HPO42- ion are the 2 that make it an ion.
PO4 3- is the phosphate ion If you add the total number of valence electrons you will get 32 as an answer. When you draw the bohr diagram of the ion you will find that the ion satisfies the octet rule. From the diagram below, you can see that ion will be a tetrahedral.

Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
A chloride ion has 18 electrons, giving it a valence of -1.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Three electrons
Chlorine has 7 valence electrons. A chloride ion has 8.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
8
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
32 electrons
