Question

Electronegativity and electropositivity are two trends of the elements of the modern periodic table where:
A. Electropositive character of elements decreases moving down a group.
B. Electronegative character of elements increases moving down a group.

• A. A is false B is false
• B. A is true B is false
• C. A is true B is true
• D. A is false B is true

Answer 1

The correct option is A A is false B is false

Down the group electropositive character increases as the atomic radius increases down the group, then the atom's ability to lose electrons increases. So, electropositive nature increases down the group.
Down the group electronegative character decreases as the radius increases then the atom's ability to attract electrons decreases, so the electronegative character decreases.
