Hi


While reading in my chem book I read somewhere that said the Li 2+ electron config has 1 electron in the 2s orbital, but if the S block elements lose electrons from the highest n value orbital shouldnt it be 1s1 rather then 2s1?

I couldnt find this exception anywhere.

Li is a group 1 element and gives one electron.

Li has electronic configuration 1s² 2s¹. In the chemical reactions Li loss 2s¹ electron only.
But during physical ionization it can loss other electrons.
