Very, tho reactivity decreases down the group
The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
Bromine is chemically active. It is a halogen and readily forms compounds with other elements, making it reactive in chemical reactions.
The halogens are the family of elements that contain the most active nonmetals. They are located in Group 17 of the periodic table and include elements such as fluorine, chlorine, bromine, and iodine. Halogens are highly reactive due to their strong tendency to gain an electron to achieve a full outer electron shell.
Phosphorus is chemically active because it readily forms compounds with other elements. It has multiple oxidation states and can react with oxygen, sulfur, and various metals to form a wide range of compounds.
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
Halogens
Fluorine is the most chemically active halogen due to its small atomic size and high electronegativity, which allows it to readily react with a wide variety of other elements.
Noble gases are all gases and not solids. In addition they are generally chemically inert as they have completely filled orbitals. Also the most active solids are generally found in group 1
halogens
Covalent Bond. Chemically Active. The only elements that are inert are group 18, or 8A.
Fluorine
Halogens are very reactive both physically & chemically than that of inert gases ,as halogens have valency 1.
The most active metals are alkali metals.The most active nonmetals are halogens.
halogens
Halides are the most active nonmetals on the periodic table because it has high electronegativity. Meaning it is more likely to attract an electron towards itself to react.
Halogens are more chemically reactive compared to noble gases. Halogens have a high tendency to gain an electron to achieve a stable electron configuration, while noble gases already have a full outer electron shell and are therefore less likely to react with other elements.
