$3^{rd}$ period contains $18$ elements

Vedclass · Answer

(B) The $3^{rd}$ period of the periodic table contains $8$ elements ($Na$ to $Ar$).Therefore,the statement that the $3^{rd}$ period contains $18$ elements is incorrect.The $1^{st}$ period contains $H$ and $He$,both of which are non-metals.The $7^{th}$ period is incomplete,and while $Og$ $(Oganesson)$ is an inert gas,it is often considered part of the $7^{th}$ period,but historically,the statement refers to the lack of naturally occurring inert gases in that period.The $p-$block contains all three types of elements: metals,non-metals,and metalloids.
