I believe it's halogens
Hydrogen reactivity can be considered relatively high, particularly in its molecular form (H₂), as it readily reacts with many elements, including oxygen to form water. Its reactivity is influenced by its position in the periodic table, where it can act as both a nonmetal and a metal under different conditions. Additionally, hydrogen's ability to form bonds with a variety of elements contributes to its role in numerous chemical reactions. However, in its diatomic form, H₂ is stable and not highly reactive under standard conditions.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
The smallest and most reactive nonmetal in Group VIA (also known as Group 16) is oxygen. Due to its high electronegativity and small atomic size, oxygen readily forms bonds with other elements, making it highly reactive. Its reactivity is particularly notable in combustion reactions and when it combines with metals and nonmetals to form oxides.
Nonmetals are elements that tend to gain electrons in chemical reactions. They typically form negative ions (anions) by accepting electrons from other elements. Nonmetals are generally located on the right side of the periodic table.
Nitrogen generally has low reactivity due to its stable triple bond in the N₂ molecule, which makes it inert under standard conditions. However, at high temperatures or in the presence of catalysts, nitrogen can react with other elements, such as hydrogen, to form compounds like ammonia. Overall, nitrogen's reactivity is relatively low compared to other elements.
The nonmetal group containing chlorine and iodine is the halogen group, which is located in group 17 of the periodic table. Halogens have high reactivity and readily form compounds with other elements. Chlorine and iodine, along with fluorine and bromine, are known members of this group.
Bromine, chlorine, and fluorine are examples of halogens, which are a group of reactive nonmetal elements located in group 17 of the periodic table. They are known for their high reactivity and ability to form salts with metals.
HON stands for "Halogens, Oxygen, Nitrogen" - which are the most electronegative elements in the periodic table. In organic chemistry, functional groups containing halogens, oxygen, or nitrogen are often referred to as HON functional groups due to their high reactivity and importance in determining the chemical properties of a molecule.

Very reactive elements are alkali metals and halogens.
The other highly reactive element in period 2 is fluorine, a non-metal. Both lithium and fluorine readily form compounds due to their high reactivity.
Potassium is an example of a substance with high reactivity due to its tendency to readily react with water or oxygen. This reactivity is due to its outer electron configuration, which makes it highly reactive in forming bonds with other elements.
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.
neon is a noble gas therefore its a non metal
Bromine is a nonmetal because it lacks the properties of a metal, such as high electrical conductivity and malleability. It is instead a halogen in group 17 of the periodic table, sharing characteristics like low melting point and high reactivity with other nonmetals.

Due to its high electronegativity and small atomic size, oxygen readily forms bonds with other elements, making it highly reactive.
