Because
Elements from group 1 (alkali metals) and group 7 (halogens) are highly reactive due to their electronic configurations. As a result, they tend to form compounds easily to achieve more stable electron configurations. Compounds with these elements often exhibit useful properties in various chemical reactions and industrial applications.
Group 7 elements (such as halogens) and group 1 elements (alkali metals) are highly reactive and tend to form compounds rather than exist in their pure elemental forms in nature. This is because they have a strong tendency to react with other elements to achieve a more stable electron configuration.
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.
Halide compounds are typically formed by combining halogen elements from Group 17 with other elements or compounds, such as metals. Group 17 elements, also known as the halogens, include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
The group you're thinking of is group 1, the alkali metals. They include sodium and potassium, and you're right, they are so reactive that they do not exist by themselves. They only exist in compounds with other elements.

group 17
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
Fluorine is so chemically active that it occurs naturally only in compounds. It is the most electronegative element, meaning it readily forms bonds with other elements to achieve a stable electron configuration.

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.
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 transition metals often produce colorful compounds.
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
