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, #"Ne"#.

The electron configuration of the noble gas neon, #"Ne"# is #"1s"^2"2s"^2"2p"^6"#.

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

#"Mg"^(2+):# A magnesium ion has 10 electrons arranged in the following ground state configuration: #"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.
