Li + express your answer in complete form, in order of increasing orbital. for example, 1s22s2 would be entered as 1s^22s^2.

Lithium with symbol Li has an atomic number of 3.

First energy shell has s orbital and can hold up to 2 electrons. Second energy shell has s orbital and p orbital and altogether 2nd energy shell can hold upto 8 electrons.

Li electronic configuration is 1s^2 2s^1

Li has one electron in the outer shell, to become stable it loses that electron.

As Li loses one electron, its net charge becomes + 1

electronic configuration of Li⁺ - 1s^2
