Down the group, size increases. Because number of shells increases.
8a group is the group in which the atoms "try to be like."
The atomic radius decrease from left to right in the periodic table.
A group in periodic table is the column of element in periodic table
Only chemical elements are placed in the periodic table; cations are positive charged atoms.
The alkaline earth group has two valence electrons.

atoms in a group have the same number of valence electrons
They are the same
Yes. Atoms get larger as they move downward in a column of periodic table. This is because of increase in number of shells down the group.

Group 18, starting with Helium
The atomic radius decrease from left to right in the periodic table.
Group 17 elements, also known as halogens, give off the most energy when forming negative ions. This is because halogens have a high electron affinity, meaning they strongly attract additional electrons to achieve a stable electronic configuration.
The noble gases in group 18 are inert.
