Question

Which of the following elements is the least metallic?

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

Answer 1

The correct option is C Palladium (Pd)

Scandium (Sc) lies in the $3^{rd}$ group and $4^{th}$ period
Mangenese (Mn) lies in the $7^{th}$ group and $4^{th}$ period
Palladium (Pd) lies in the ${10}^{th}$ group and $5^{th}$ period
Platinum (Pt) lies in the ${10}^{th}$ group and $6^{th}$ period

Metallic character increases down the group and decreases along the period.
Therefore, Palladium has the least metallic character.
