What is the electron configuration of Mg 2 +?

For example, lithium forms Li+, with the 1s2 configuration, magnesium forms Mg2+, with the 2s22p6 configuration for its highest energy electrons, and chlorine forms Cl-, with the 3s23p6 configuration.

Then, what is the electron configuration of mg2+?

The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.

Secondly, what does mg2+ represent? Mg2+ is a Mg atom that now has the same number of electrons as a noble gas. It achiveved this by giving up to other atoms in its vicinity who could be considered “electron acceptors”: they are atoms from chemical elements that are ready to accept these electrons to reach the configuration of a noble gas.

what does the 2+ mean in mg2+?

Mg atom consists of 12 electrons with the electronic configuration as 2, 8, 2 . Mg2+ means 2 positive charge, which means 2 electrons are lost, thus no. of electrons remaining in the atom is 12–2=10 . So no. of electrons in Mg2+ is 10.

What is the electron configuration of Li+?

of Li+: 1s2; electron config. of Be+: 1s22s1.
