How many unpaired electrons are there in an atom of an element with the following electronic configuration? 1s22s22p6

How many unpaired electrons are there in an atom of an element with the following electronic configuration? 1s²2s²2p₆

Answer Details

An atom with the electronic configuration 1s²2s²2p₆ has a completely filled valence shell, which means that all of its electrons are paired. Therefore, the number of unpaired electrons in this atom is zero (0).
