Question 4

In the modern periodic table, how do electronegativity and metallic character generally change as one moves from left to right across a period?

Accepted Answer

B. Electronegativity tends to increase, while metallic character tends to decrease. — Across a period from left to right, the nuclear charge increases and the atomic radius generally decreases, leading to a stronger attraction for valence electrons, hence electronegativity increases. Concurrently, the tendency to lose electrons decreases, and the tendency to gain electrons increases, causing the metallic character to decrease and non-metallic character to increase.

Answer

A. Both electronegativity and metallic character tend to increase.

Answer

C. Electronegativity tends to decrease, while metallic character tends to increase.

Answer

D. Both electronegativity and metallic character tend to decrease.
