ColumnsColumns
The columns on The columns on the Table are the Table are called called groupsgroups. .
The groups areThe groups arenumbered from numbered from 1-1-1818. .
Elements within Elements within a group have a group have very similar very similar propertiesproperties..Make this symbol on your Periodic Table:

direction of the periodsdirection of the periods..
Across any period, the properties of
elements gradually change. For
example, as you move from left to right across the
table, atoms tend to become smaller in size, but larger in
mass.
