# Hat is the charge of the ion most likely to be formed from Magn to achieve noble gas notation?

Dec 5, 2016

The magnesium ion will have a charge of ${2}^{+}$ and will have the electron configuration of the noble gas neon.

#### Explanation:

Magnesium ions have a charge of ${2}^{+}$, due to the loss of its two valence electrons, giving it the noble gas configuration of neon, $\text{Ne}$.

The electron configuration of the noble gas neon, $\text{Ne}$ is $\text{1s"^2"2s"^2"2p"^6}$.

$\text{Mg}$: A neutral magnesium atom has 12 electrons arranged in the following ground state configuration: $\text{1s"^2"2s"^2"2p"^6"3s"^2}$>

${\text{Mg}}^{2 +} :$ A magnesium ion has 10 electrons arranged in the following ground state configuration: $\text{1s"^2"2s"^2"2p"^6}$.

This only occurs if magnesium is involved in ionic bonding , in which one or more electrons are transferred to one or more negatively charged ions.
