The electron configuration of the phosphide ion (p3-) is .

The electronic configuration is given below.

Explanation:

Electronic configuration tells us about the number of electrons that are present in an atom. It also determines the atomic number of an element.

Phosphorus is the 15th element of the periodic table having 15 electrons.

The electronic configuration for the given element =

This element require 3 electrons and thus carry a charge of -3 units.

So, the electronic configuration for the phosphide ion which is formed by gaining 3 electrons =

Thus, the electronic configuration is given above.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
