Question

Find the elements Which is the least metallic?

• A. $Scandium\left(Sc\right)$
• B. $Platinum\left(Pt\right)$
• C. $Palladium\left(Pd\right)$
• D. $Mangenese\left(Mn\right)$

Answer 1

The correct option is C $Palladium\left(Pd\right)$

As We Know,
$Scandium\left(Sc\right)$ lies in the $3^{rd}$ group and $4^{th}$ period $Mangenese\left(Mn\right)$ lies in the $7^{th}$ group and $4^{th}$ period $Palladium\left(Pd\right)$ lies in the ${10}^{th}$ group and $5^{th}$ period $Platinum\left(Pt\right)$ lies in the ${10}^{th}$ group and $6^{th}$ period.

Metallic character increases down the group and decreases along the period.This is because atoms have a better ability to gain electrons to fill a valence shell than lose them to and an unfilled shell.Therefore, Palladium has the least metallic character.
Hence, Correct Option is $c$
