Why are the alkali metals and the halogens among the reactive elements an the periodic table?

alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.

∙ 15y agoAlkaline metals are reactive because they contain one electron in their outer shell. Halogens are reactive because they contain seven electrons in their outer shell. The closer the number is to one or seven, the more reactive the element is. Elements with eight electrons in their outer shell show little or no reactivity.

∙ 13y agoThe basic reason is that the alkali metals have only 1 electron to lose to become stable and the halogens have only 1 electron to gain to become stable. The vast majority of the other elements have more than 1 electron to lose or gain. This takes more energy and makes them less reactive.

∙ 13y agobecause to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
