group 18 has completely filled electronic configuration and hence are stable.
group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
many compounds are found
Elements in group 1 of the periodic table, such as sodium and potassium, are highly reactive due to their single valence electron. In nature, they are found in compounds as opposed to pure elemental form because they readily react with other elements to form stable compounds.
There are 4 elements in group-4.
When group 1 elements (such as lithium, sodium, potassium) react with nonmetal elements, they typically form ionic compounds. These compounds consist of a metal cation from the group 1 element and a nonmetal anion, resulting in salts like lithium chloride (LiCl), sodium fluoride (NaF), or potassium iodide (KI).
Group 3 of the periodic table contains many of the radioactive elements.

No, carbon is not unusual in forming few compounds with other elements. In fact, carbon is known for its ability to form a wide variety of compounds with other elements due to its versatile bonding capabilities. Carbon can form numerous compounds with many different elements, giving rise to the complexity and diversity found in organic chemistry.
All compounds are made of two or more elements.
This situation is normal. The number of chemical elements is smaller compared to the number of chemical compounds.
Two or more elements.
Common elements found in organic compounds include carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements form the building blocks of organic molecules and are essential for the structure and function of living organisms.
There are far more compounds than elements: Fewer than 200 elements and many million distinct compounds.
Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
