Question

An element has electronic configuration 1s²2s22p63s²3p4523d104 p. Then it
is in...........group​

Answer 1

$\mathsf\red{1{s}^{2} 2{s}^{2} 2{p}^{6} 3{s}^{2} 3{p}^{4}}$

$\mathsf\blue{It \: belongs \: to \: p− block \: since \: last \: electron \: is \: filled \: in \: p− orbital}$

$\mathsf\blue{and \: belongs \: to \: {3}^{rd} \: period \: as \: n=3.}$

$\mathsf\red{Electronic \: configurations \: belongs \: to \: {16}^{th} \: group.}$
