Want this question answered?
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
Periods go across the periodic table. Groups go down.
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
there are alot of groups in the periodic table. to many to mention but each element is grouped into is like chemicals generally down the periodic table. heres a link which will give you all the groups and there properties http://en.wikipedia.org/wiki/Group_%28periodic_table%29
families determine the energy level of an element and groups determine their properties.
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.

From right to left (1- 18) on the periodic table. Instead of up and down (1-7) periods go vertically. (rows) groups go horizontally. (columns)
As the orientation goes down, the elements become more solid. :-)
As with any grid, the periodic table has rows running left to right, and columns running up and down. The rows are called PERIODS and the columns are called GROUPS.

Ionisation energy decreases down the group. It is easy to remove an electron.
