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.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
