Vedclass · Answer

(C) Representative elements are the elements belonging to the $s$-block and $p$-block of the periodic table (excluding noble gases in some definitions,but generally including them as $p$-block elements).$s$-block elements have the valence shell configuration $ns^{1-2}$.$p$-block elements have the valence shell configuration $ns^2 np^{1-6}$.Combining these,the representative elements (main group elements) are characterized by the valence shell configuration $ns^{1,2} np^{0-6}$ (where $np^0$ represents $s$-block elements and $np^{1-6}$ represents $p$-block elements).

Which of the following electronic configurations represents representative elements?
