Answer:
have similar properties
Explanation:
Elements in a column of the periodic table have similar chemical properties.
A periodic column is also called a group or family.
- Chemical properties are determined by the valence electrons.
- The number of valence electrons determines how atoms chemically combine.
Elements in the same group has the same number of valence electrons.
Therefore, they will combine chemically the same way.
This is not so for the periods on the periodic table.
