Back

It increases.

Front

What factor affects Coulombic attraction in atoms of the same valence energy level?

Back

Number of protons/Zeff.

Front

Front

What is electronegativity?

Back

The ability of an atom to attract electrons from another atom.

Front

Define effective nuclear charge (Zeff).

Back

The net positive charge experienced by an electron in a multi-electron atom.

Front

How does atomic radius change across a period?

Back

It decreases from left to right.

Front

What is the trend of ionization energy down a group?

Back

It generally decreases.

Front

What is the relationship between electronegativity and ionization energy?

Back

Higher electronegativity usually correlates with higher ionization energy.
