Periodic Table Families

An atom that has 5, 6, 7, or 8 valence electrons is likely to be:

• an alkali metal atom

• an alkaline earth metal atom

• a non-metal atom

• a transition metal atom

Which statement is true about the carbon family?

• They are all non-metals.

• They all have four valence electrons.

• They are all metals.

• They do not react with other elements.

The ten short columns in the middle of the periodic table are called:

• alkali metals

• noble gases

• halogens

• transition metals

Which family in the periodic table is known for having elements with a single valence electron?
