Question

The electronic configurations of the elements $X,Y,Z$ and $J$ are given below. Which element has the highest metallic character?
$X=2,8,4$
$Y=2,8,8$
$Z=2,8,8,1$
$J=2,8,8,7$

• A. $X$
• B. $Y$
• C. $Z$
• D. $J$

Answer 1

The correct option is C $Z$

Metallic character increases down a group and decreases in a period as we move from left to right. So, alkali metals have the highest metallic character and $Z=2,8,8,1$ is electronic configuration of alkali metals. Therefore, element $Z$ has the highest metallic character.
