Based on the electron configuration of the elements below, answer the question. , where the upper index is atomic mass and the lower index is atomic number. How many electrons are present in a Phosphorus 3⁺ ion?

The answer to your question is 12

Explanation:

Data

Number of electrons in Phosphorus 3+ ion

Process

1.- The sign of the number after the name indicates if the element has lost or gained electrons.

If the sign is positive the element has lost electrons

If the sign is negative the element has gained electrons.

2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.

they are both synthetic elements
