Vedclass · Answer

(A) The outermost shell is the valence shell $(n)$.For $s$-block elements,the general configuration is $ns^{1-2}$,so the maximum electrons in the outermost shell is $2$.For $p$-block elements,the general configuration is $ns^2 np^{1-6}$,so the maximum electrons in the outermost shell $(ns + np)$ is $2 + 6 = 8$.For $d$-block elements,the general configuration is $(n-1)d^{1-10} ns^{0-2}$. The outermost shell is $ns$,which can have a maximum of $2$ electrons.For $f$-block elements,the general configuration is $(n-2)f^{1-14} (n-1)d^{0-1} ns^2$. The outermost shell is $ns$,which has a maximum of $2$ electrons.Thus,the maximum number of electrons in the outermost shell for $s, p, d$,and $f$ block elements are $2, 8, 2, 2$ respectively.

Maximum number of electrons in the outermost shell of $s, p, d$,and $f$ block elements are respectively:
