It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
The noble gases in group 18 of the periodic table do not usually form compounds with other elements. Under very unusual circumstances in the laboratory, chemists have forced many of these elements to actually make compounds but none of the noble gases make compounds under normal conditions.
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
Group 16 on the Periodic Table, also known as the chalcogens, contains elements that react with oxygen to form compounds with the general formula X2O. The elements in this group include oxygen, sulfur, selenium, tellurium, and polonium.
The elements in the group known as the halogens (Group 17) are always linked with others to form compounds due to their high reactivity and tendency to gain an electron to achieve a stable configuration. This group includes elements like chlorine, fluorine, and iodine.
Yes, generally compounds of group 1 elements (such as lithium, sodium, and potassium) are soluble in water. This is because they form ionic compounds with water, leading to dissociation into ions which increases solubility.
Periodic table group elements with similar properties together. It makes study of elements easier for chemists.

The transition metals tend to form colored compounds.
Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
The noble gases in group 18 of the periodic table do not usually form compounds with other elements. Under very unusual circumstances in the laboratory, chemists have forced many of these elements to actually make compounds but none of the noble gases make compounds under normal conditions.

Group 16 on the Periodic Table, also known as the chalcogens, contains elements that react with oxygen to form compounds with the general formula X2O. The elements in this group include oxygen, sulfur, selenium, tellurium, and polonium.
Boron is the only element in group 13 that is a metalloid, meaning it shares properties of both metals and nonmetals. It has a unique structure due to its small atomic size and high ionization energy compared to its group members. Boron also forms covalent compounds instead of ionic compounds like other group 13 elements.
The transition metals often produce colorful compounds.
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
