on their own they are too reactive to be used therefore togethor they would work
They both lose or gain an electron easily therefore form compounds
Groups 1 and 17.
no one ahs heard about it
because god made it that way.
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
Because
In chemical education it is the most siplest start for explaining reaction equations: they react 1 to 1.
Elements on opposite sides of the periodic table, for example Groups 1 and 17, form ionic compounds. Examples include LiCl, NaCl, KI, and RbBr. The elements in Group 1 are the alkali metals, and the elements in Group 17 are the halogens, which are nonmetals.
The element's group's 1 to 7 are : 1)Hydrogen 2) Heline 3)Lithiume 4)Bery limb 5)Born 6)Carbon 7) Nitrogen 8)Oxygen 9) Florine 10)Neon _______________________________________________________________ i think so 1 to 15 are almost used in the compounds. Thank You,
Groups 1 and 17.
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.

Group 1 and 2 elements have 1 and 2 valence electrons respectively. Removal of these electrons will result in stable noble gas electronic configuration. Group 17 and 16 elements have 7 and 6 valence electrons respectively. Addition of 1 or 2 electrons to group 17 and 16 respectively will give them stable noble gas configuration. Hence these two groups are highly reactive and their elements will combine to form large number of compounds.
