The electronic configurations of these atoms are:

O\ have\ 1s^2\ 2s^2\ 2p_x^2\ 2p_y^1\ 2p_z^1\\ 2\ unpaired\ electrons\ in\ 2p_y^1\ and\ 2p_z^1. \\ \\Cl\ have\ 1s^2\ 2s^2\ 2p^6\ 3s^2\ 3p_x^2\ 3p_y^2\ 2p_z^1\\ 1\ unpaired\ electron\ in\ 3p_z^1. \\ \\N\ have\ 1s^2\ 2s^2\ 2p_x^1\ 2p_y^1\ 2p_z^1\\ 3\ unpaired\ electrons\ in\ 2p_x^1\ 2p_y^1\ and\ 2p_z^1. \\ \\ Ne\ have\ 1s^2\ 2s^2\ 2p_x^2\ 2p_y^2\ 2p_z^2\\ No\ unpaired\ electrons.\\ \\So\ Ne\ has\ all\ electrons\ spin\ paired.
