Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

Do cations lose or gain electrons?

Back

Cations lose electrons.

Front

What is atomic radius?

Back

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

Front

Which element has the largest atomic radius: H, N, Cl, or Cs?

Back

Cs (Cesium) has the largest atomic radius.

Front

What is the trend in atomic radius across a period?

Back

Atomic radius decreases from left to right across a period due to increasing nuclear charge.

Front

What is the trend in atomic radius down a group?

Back

Atomic radius increases down a group due to the addition of electron shells.
