Question

question 8 of 10
the periodic trend for electronegativity is similar to what other trend?

a. the trend for atomic radii

b. the trend for ionic radii

c. the trend for shielding.

d. the trend for first ionization energy

Explanation:

Electronegativity generally increases across a period (from left to right) and decreases down a group. First ionization energy also increases across a period (as it's harder to remove an electron from a more electronegative atom with a stronger hold on electrons) and decreases down a group (as electrons are further from the nucleus and easier to remove). Atomic radii and ionic radii generally decrease across a period and increase down a group (opposite to electronegativity). Shielding effect generally increases down a group (as more electron shells are added) and stays relatively constant across a period (not matching electronegativity trend). So the trend of electronegativity is similar to first ionization energy trend.

Answer:

D. The trend for first ionization energy
