They are chalcogens which, as the name suggests, are ore formers. They combine with other elements to make ores.
Group 17 of the periodic table, also known as the halogens, includes fluorine, chlorine, bromine, iodine, and astatine. These elements are highly reactive nonmetals that readily form salts by gaining an electron to achieve a full outer electron shell. They are also diatomic molecules in their elemental form.
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
Elements within the same group on the periodic table have the same number of valence electrons, which influences their chemical behavior. This results in similar properties and reactivity within a group of elements.
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
The chemical elements in a group have similar properties.

Elements in group A are metals. They possess metallic behaviour.
elements in a group have the same number of valence electrons
Elements within a group always have the same number of valence electrons.
The atomic radius increases from top to bottom within a group.
It uses a different group of participants for each of the treatment conditions being compared.
