Magnesium is in Group 2 of the Periodic Table, so it has two outermost electrons. To have a full complement of e- in its outer shell, it must lose 2, hence, it becomes an Mg2+ ion.
Magnesium has to lose 2 electrons to get the noble gas configuration of the noble gas, neon.
The neutral atom of magnesium has 12 electrons; the magnesium cation (Mg2+) has 1o electrons.
Two:
Mg --> Mg2+ + 2e-
It loses 2 valence electrons.
lose 2
No. A atom is stable when it has a full valence shell. The way this works is (2,8,8,8...) For an example magnesium which has 12 electrons. Magnesium loses 2 electrons ( so it has 2, 8 and then has a full outer shell) to gain a full outer charge which results in a charge of 2+.
no its outside shell has 10/18 electrons
Atoms often form ions by losing or gaining enough electrons to end up with a full outer shell. How many electrons are in a full outer shell for most atoms? Don't know? How about Googling full outer shell?
Eight - it has a full outer shell of electrons.
Electron outer shell tee hee =^-^=
it needs six more electrons to have a full outer valence shell.

Magnesium chloride is an ionic compound. Magnesium has 2 valence electrons, and chlorine has 7. According to the octet rule, each element will bond in such a way that it ends up having 8 electrons in its outer shell--either by adding electrons to its outer shell until it has 8, or by losing all the electrons in its outer shell (that way, the next-largest electron shell--which is already full--becomes the new outer shell). Since magnesium has 2 valence electrons, it will lose two electrons (it's easier to go 2 - 2 = 0 than to go 2 + 6 = 8). Chlorine has 7, so it will gain an electron and have a full (8-electron) outer shell. There must therefore be two chlorines for every magnesium: each chlorine accepts one of the two electrons donated by magnesium. Magnesium forms two ionic bonds: one to each chloride ion.
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
It has a full outer shell of electrons
Magnesium, in the second group, can either gain six electrons or lose two electrons to achieve a full outer shell.
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
It has a full outer shell of electrons.
Yes it is . The outer argon is full becoz it has 18 electrons
no its outside shell has 10/18 electrons

Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
