Identify the correct statements from the following.

Step-by-step solution

( Alkali metals are strong reducing agents because after the removal of the only valence electron (n s^1 ) they can gain the electronic configuration of noble gases (n-1) p^6 , that is more stable electronic configuration. KO ₂ is paramagnetic oxide due to the presence of 1 unpaired electrons. The number of electrons present is 17 where the sixteen electrons are from two oxygen atoms and one from the negative charge ( O ₂⁻ ) . Its molecular orbital configuration can be written as aligned & 1 s^2 * 1 s^2 2 s^2 * 2 s
