Question

use the periodic table to answer the following questions.
how many valence electrons does magnesium have? 2
complete
type in the correct values to correctly represent the valence electron configuration of magnesium: as$^b$
a= 3
b= 2
complete
what is the charge of a magnesium ion? +

Explanation:

Step1: Recall magnesium's valence electrons

Magnesium has 2 valence electrons.

Step2: Relate valence electrons to ion charge

To achieve a stable octet, magnesium loses its 2 valence electrons, resulting in a positive charge equal to the number of electrons lost.

Answer:

2
