Vedclass · Answer

(C) Alkali metals have a general electronic configuration of $ns^1$. They have a low first ionization energy $(IE_1)$ because removing the single valence electron results in a stable noble gas configuration. However,the second ionization energy $(IE_2)$ is significantly higher because it involves removing an electron from a stable,fully filled inner shell (noble gas core). Comparing the options: $X: IE_2/IE_1 = 1.1$ $Y: IE_2/IE_1 = 1.26$ $Z: IE_2/IE_1 = 2.56$ $M: IE_2/IE_1 = 1.25$ Option $Z$ shows a large jump between $IE_1$ and $IE_2$,which is characteristic of an alkali metal.

Based on the values of $IE_1$ and $IE_2$,which of the following represents an alkali metal?
