Question

Phosphorous can form an ion called phosphide, which has the formula p3−. this ion ______.phosphorous can form an ion called phosphide, which has the formula p3−. this ion ______.has properties very similar to those of pforms when a phosphorus atom loses three protonsis called a cationcontains 18 electrons

Answer 1

Explanation:

When an atom gains electrons then it tends to obtain negative charge whereas when an atom loses electrons then it tends to gain a positive charge.

Atomic number of phosphorous is 15 and it need 3 more electrons in order to complete its octet. Therefore, by gaining electrons it will result in the formation of $P^{3-}$ ion.

Thus, we can conclude that phosphorous can form an ion called phosphide, which has the formula $P^{3-}$. This ion contains 18 electrons.
