How many valence electrons are in MG?
By looking at both the electronic configurations, we find that the number of electrons in the outermost shell is found to be two.
What is magnesium valence number?
-We all know that the valency is the number of outermost electrons of the atom. It states the combining capacity of the atom. Therefore, the valency of Magnesium is 2.
What is valence shell of Mg?
Magnesium has atomic number 12. Its electronic configuration is 2,8,2 . Thus, it has 2 valence electrons.
How many electron shells does Mg have?
Magnesium has a total of 12 electrons – 2 in the innermost shell, 8 in the second shell, and two electrons in its valence shell (third shell).

What does Mg stand for in elements?
magnesium (Mg), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table, and the lightest structural metal. Its compounds are widely used in construction and medicine, and magnesium is one of the elements essential to all cellular life.
How many valence electrons does the ion Mg 2 +} have?
So if you add them up, then subtract two to account for the 2+ ionic charge, you will get the right number of electrons. In either case, you will end up with 12−2=10 electrons.
