Vedclass · Answer

(B) Alkali metals have the general electronic configuration $ns^1$. When they form salts (e.g.,$M^+X^-$),the metal ion $M^+$ achieves a stable noble gas configuration $(ns^2 np^6)$.Since all electrons in the $M^+$ ion are paired,the salts are diamagnetic.Furthermore,because there are no unpaired electrons to undergo $d-d$ transitions or charge transfer,these salts do not absorb visible light and are therefore colourless.
