$r_{Mg} < r_{Al}$

Vedclass · Answer

(B) In a period,the atomic radius decreases from left to right due to an increase in effective nuclear charge. In a group,the atomic radius increases from top to bottom due to the addition of new shells. $(A)$ $r_{Br} $(B)$ $r_{Mg} $(C)$ $r_{Rb}  r_{Na}$. $(D)$ $r_{At} Since the question asks for the incorrect trend,both $(B)$ and $(C)$ represent incorrect trends. However,in standard competitive chemistry,$r_{Mg} > r_{Al}$ is the classic example of a periodic trend error.
