Periodic Table Trends

The arrows point to the largest atomic radius.

Multiple Choice

Which periodic group has the smallest atomic radius?

• Alkali metals
• Halogens
• Noble Gases
• Transition metals

Multiple Choice

The atom with the largest atomic radius in Group 18 is - 

• Ar
• He
• Kr
• Rn

Multiple Choice

As you move down the periodic table atoms get bigger.  This is because ____________.

• The atoms have more mass.
• The atoms have more protons.
• The atoms have more energy levels
• The atoms have more nuetrons

Multiple Choice

Which atom has the largest atomic radius?

• potassium

• rubidium

• francium

• cesium

These lose electrons to have a full outer shell.

These gain electrons to have a full outer shell.

Groups 1-14 tend to form cations (lose e-).

Groups 15-17 tend to form anions (gain e-).

Group 18 does not form ions.

Anions as always larger than cations.

If comparing with other cations/anions, the trend is to the left and down.
