Question

Show the determination of the charge of the ion formed by the Mg12 atom.

Answer 1

Step-by-step explanation:

It is known that the atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2. And, in order to attain stability a magnesium atom will tend to lose its valence electrons.

That is, being a metal magnesium atom will lose its 2 valence electrons and hence it forms a
`Mg^(2+)` ion.

Equation for this type of loss is as follows.

`Mg \rightarrow Mg^(2+) + 2e^(-)`

Therefore, we can conclude that the charge of the ion formed by the
`_(12)Mg` atom is +2.
