∙ 11y agogroup 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.

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.

There are 4 elements in group-4.
Common compounds of magnesium include magnesium oxide (MgO), magnesium chloride (MgCl2), magnesium sulfate (MgSO4), and magnesium hydroxide (Mg(OH)2). These compounds are used in various applications ranging from healthcare to industrial processes due to magnesium's diverse properties.

All compounds are made of two or more elements.
Elements on opposite sides of the periodic table have different properties due to their distinct chemical behaviors. For example, metals are often found on the left side of the table and tend to be good conductors of electricity, while nonmetals on the right side are typically poor conductors. The transition metals in the middle have characteristics of both metals and nonmetals.
This situation is normal. The number of chemical elements is smaller compared to the number of chemical compounds.
Two or more elements.
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.
