Question

Classify the element platimun (Pt) on the basis of its valency.

Answer 1

Valency: When an element combines with other atoms to form chemical compounds or molecules, its valency is defined as its combining power.

• The periodic table's 78th element is platinum. It is classified as a transition metal because it is found in the d-block of the periodic table.
• The oxidation state or valency of transition metals can be changed.
• Platinum's electrical configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s¹ 4f¹⁴ 5d⁹ or [Xe]6s¹ 4f¹⁴ 5d⁹ .
• It has a 4 or 2 valency.
