Compounds of unipositive ions are paramagnetic.

Vedclass · Answer

(B) Group-$1$ elements (alkali metals) have a general electronic configuration of $ns^1$. Upon losing one electron,they form unipositive ions $(M^+)$ with a stable noble gas configuration $(ns^2np^6)$,which are diamagnetic because all electrons are paired. Therefore,the statement that compounds of unipositive ions are paramagnetic is incorrect. They form colourless compounds in the $+1$ state because they lack unpaired electrons. They are strong reducing agents and possess high negative values of standard reduction potential.
