Question

The electronic configurations of the elements $X,Y,Z$ and $J$ are given. Which element has the highest metallic character?

• A. $X=2,8,4$
• B. $Y=2,8,8$
• C. $Z=2,8,8,1$
• D. $J=2,8,8,7$

Answer 1

The correct option is C $Z=2,8,8,1$

s-block element has the highest metallic character as they can easily lose their valence electrons.

Here the element $Z$ is a s-block element as it is clear from its electronic configuration which is $2,8,8,1$ i.e.$\left[Ar\right]4s^1$.
