Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right across a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom within a group.

Front

What makes a valence electron more attracted to the nucleus?

Back

Less distance between the nucleus and having more protons increases attraction.
