Question

In the periodic table, with the increase in atomic number, the metallic character of an element

• A. decreases in a period and increases in a group
• B. increases in a period and decreases in a group
• C. increases both in a period and the group
• D. decreases in a period and the group.

Answer 1

Answer: (A)

Metallic character increases from the top to bottom in a group as a tendency to lose electrons increases. This increases the electropositive character and metallic nature.
Metallic character decreases in a period from left to right. It is because the ionization energy increases in a period. This decreases the electropositive character and metallic nature.
