Vedclass · Answer

(B) The general trend for ionization energy increases from left to right across a period and decreases down a group.For the elements $Li, Be, B,$ and $Na$,the order is determined by their electronic configurations:$Li: [He] 2s^1$$Be: [He] 2s^2$$B: [He] 2s^2 2p^1$$Na: [Ne] 3s^1$$Na$ has the lowest ionization energy as it belongs to the third period.Between $Li, Be,$ and $B$,$Be$ has a higher ionization energy than $B$ due to the stable,fully-filled $2s$ subshell.Thus,the correct order is $Be > B > Li > Na$.

What is the correct order of the first ionization energy for $Li, Be, B,$ and $Na$?
