Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

How does electronegativity change across a period?

Back

Electronegativity generally increases across a period.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group.
