Neither. Chlorine is among the most highly reactive nonmetal elements, but fluorine and oxygen are even more reactive, as are the heavier alkali and alkaline earth metals.
Group 17, also known as the halogens, consists of the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). In order from least reactive to most reactive, the elements are iodine, bromine, chlorine, and fluorine, with astatine being the least reactive among them. Fluorine is the most reactive halogen due to its high electronegativity and small atomic size.
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.
The reactivity of an element increases towards the top and right of the periodic table (until the column of noble gases is reached). Chlorine's outer shell contains 7 electrons that make it very reactive. Helium is a noble gas and is non reactive. Elements found in the middle of the table, like nickel and iron, are reactive, but less reactive than chlorine
The most reactive p-block elements are the halogens - fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive due to their strong tendency to gain an electron to achieve a stable electron configuration.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Chlorine is a Highly reactive element.
Oxygen and chlorine would be the most chemically reactive, as they readily form compounds with other elements. Argon and neon are inert gases, meaning they are stable and do not readily react with other substances.
Oxygen and chlorine would be the most chemically reactive gases due to their high electronegativity and tendency to gain or share electrons with other elements. Argon and neon, being noble gases, are already stable and do not readily react with other elements.
Chlorine and lithium would be the most reactive because chlorine is a halogen and lithium is an alkali metal, both of which are highly reactive elements. Nickel is a transition metal and is less reactive compared to chlorine and lithium.
Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.

Fluorine, oxygen, chlorine.
The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.
Fluorine is the single most reactive nonmetal, with oxygen and chlorine close behind.
Fluorine and oxygen are the most chemically reactive nonmetals. Fluorine is the most reactive nonmetal, readily reacting with almost all other elements, while oxygen is highly reactive and forms compounds with most elements in the periodic table.
Chlorine was isolated before fluorine because it is more reactive and abundant, which made it easier to isolate and study. Fluorine is the most reactive of all elements and is rarely found in its elemental form in nature, making it more challenging to isolate.
