Question

Lead has only one valency.

• A. True
• B. False

Answer 1

The correct option is B False

• An atom’s combining capacity is known as its valency. The valency of the element represents the number of bonds that an atom can form as part of a compound.
• Lead(Pb) is an element of the periodic table with an atomic number of 82. The electronic configuration of Pb is
• Pb = [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p²
• The valencies of lead (Pb) are 2,4. Valencies of lead are +2 or +4.
• Hence given statement is false.
