Group 17 or halogens will combine readily with group 1 elements.
Groups 1 and 17.
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.
Alkaline Earth metals
Hemoglobin combines readily with oxygen.
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.

reactivity
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.
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.
Mostly group 1 metals like sodium or potassium
Yes, hydrogen is reactive because it readily combines with other elements to form compounds.
In general, when an element in group 1 or group 2 combines with elements in group 16 or group 17, ionic bonds are formed between the two elements.
