Front

What happens to electron affinity as you move from left to right across a period?

Back

Electron affinity increases.

Front

Which element has greater ionization energy: Magnesium or Phosphorus?

Back

Phosphorus has greater ionization energy.

Front

Why does the atomic radius decrease as you move from left to right across the periodic table?

Back

The number of protons increases, so attraction to electrons increases.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.
