The group is the column and the period is the row. Group numbers run across the top of the Periodic Table, and period numbers run down the left side. Group tells you the number of valence electrons and period tells you the energy level that those valence electrons are in.

What does ga mean on the periodic table?
Ga stands for Gallium . It is present in group-13 of the periodic table.
What happens to the pull on the electrons in the Periodic Table?
The pull on electrons in the Periodic Table increases from left to right across a period due to increasing effective nuclear charge. From top to bottom within a group, there is less pull on the electrons as electrons are added to higher energy levels further away from the nucleus.
What does the number at the top of each column in the periodic table mean?
The number at the top of each column in the periodic table is the group number. It indicates the number of valence electrons an element in that column has, which influences its chemical properties. Elements in the same group tend to have similar chemical behavior due to their shared number of valence electrons.
What does ir mean in the periodic table?
