Density increases across a period and decreases down a group as atomic number increases.

Vedclass · Answer

(A) Statement $A$ is incorrect. In a period,density generally increases with atomic number,but down a group,density increases because the increase in atomic mass is more significant than the increase in atomic volume. Statement $B$ is correct; ionization energy depends on the penetration effect of orbitals $(s > p > d > f)$. Statement $C$ is correct; electron gain enthalpy generally becomes less negative (decreases) down a group. Statement $D$ is correct; diagonal relationship explains the similarity in properties like charge-to-size ratio between elements of the second and third periods.

Column-$I$	Column-$II$
$A. Z = 37$	$P. p-$ block
$B. Z = 42$	$Q. f-$ block
$C. Z = 34$	$R. d-$ block
$D. Z = 92$	$S. s-$ block
