Group 1 elements have one electron in their outermost electron shell, making it easier for them to lose this electron to achieve a full outer shell. This electron loss results in the formation of positively charged ions, which readily form ionic bonds with other elements to achieve a stable electron configuration.
The Alkali Metals, which are the elements in Group 1 of the periodic table, each have one lone electron in their valence shell. And each of these elements wants to get rid of that single electron. These metals, which include lithium, sodium, potassium, rubidium, caesium and francium, are the most likely to lose electrons.
+1 only for all elements (except for hydrogen) hydrogen can have +1 and -1 as their oxidation numbers.
As a general rule, these are the elements toward the top of the group in the periodic table.
The group 1 metals, namely lithium, sodium, potassium, rubidium, cesium, and francium (although francium is exceedingly rare and unstable) all easily lose a single electron to form +1 ions. Many other metals (especially the group 2 metals) also readily give up electrons to form ions, although the group 1 elements are by far the most reactive in this regard.
Group 1 metals, such as sodium and potassium, readily combine with group 17 elements (halogens) to form salts. These metals have one electron in their outermost shell, which they can easily lose to achieve a stable electron configuration, while halogens are one electron short of a stable configuration and readily accept an electron to form a stable ion.
All group 1 elements have a +1 charge because they readily lose their outermost electron to achieve a full outer shell and attain a stable electron configuration.
Elements in Group 1 (alkali metals) readily form ions by losing one electron to achieve a stable electron configuration. This is due to their low ionization energy, which makes it easier for them to lose electrons and form positively charged ions.

Group I elements (that is alkali metals)
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
As a general rule, these are the elements toward the top of the group in the periodic table.
The group 1 metals, namely lithium, sodium, potassium, rubidium, cesium, and francium (although francium is exceedingly rare and unstable) all easily lose a single electron to form +1 ions. Many other metals (especially the group 2 metals) also readily give up electrons to form ions, although the group 1 elements are by far the most reactive in this regard.
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
Group 1 elements (such as Sodium and Potassium) readily form compounds because they are highly reactive metals that readily lose their outer electron to form positive ions. Group 7 elements (such as Chlorine and Fluorine) are highly reactive nonmetals that readily gain an electron to form negative ions, making them prone to forming compounds as well.
