Vedclass · Answer

(B) The period number of an element in the periodic table corresponds to the number of shells occupied by electrons in its atom.For elements in period $1$,the outermost shell is the $K$ shell $(n=1)$.For elements in period $2$,the outermost shell is the $L$ shell $(n=2)$.For elements in period $3$,the outermost shell is the $M$ shell $(n=3)$,and so on.Therefore,for elements of period $2$,the outermost shell is the $L$ shell.

Which of the following is the outermost shell for elements of period $2$?
