Periodic Table has 18 groups; see the link below.
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
The columns on the periodic table are called Groups.
A p3 element refers to an element in the p-block of the periodic table that has three valence electrons. This typically includes elements from groups 13 to 16, such as aluminum (Al) and phosphorus (P). These elements often exhibit unique chemical properties due to the presence of their p electrons, influencing their reactivity and bonding behavior.
The three main element groups are alkali metals , alkaline earth metals and halogen family.
groups run top to bottom periods run left to right
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
A German chemist Dobernier observed relationship between atomic masses of several groups of three elements called traids.In these groups the central or middle element had atomic mass average to the other two elements.
The columns on the periodic table are called Groups.

it is called a form
It is an old name, a synonym; groups of elemetes were compared with a family.
This element 53 is called: Iodine, diatomic element I2.
So-called NON-transition metals is not a defined group of elements, other than "All other elements that are NOT transition elements".
