Front

Define atomic radius.

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius decreases from left to right across a period.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius increases as you move down a group.

Front

Explain why atomic radius increases down a group.

Back

Because additional energy levels are added, increasing the distance between the nucleus and the outermost electrons.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.
