it needs six more electrons to have a full outer valence shell.
Magnesium needs 8 valence electrons to have a full valence shell.

Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
The outer shell is called the valence shell
There are 2 electrons in valence shell of calcium. :-)
The outer shell of an atom is the valence shell, which contains the valence electrons.
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.

A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.

outer shell electrons are knows as Valence Electrons
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Valence Electrons
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
