Q. What is the most reactive nonmetal in the periodic table?
The most reactive nonmetal in the periodic table is fluorine.
It has the highest electronegativity of any element, 3.98 on the Pauling scale. Fluorine is a highly reactive, diatomic gas that can react with almost every other element and combine to create compounds with properties that are radically different from either starting ingredient. Fluorine has a boiling point of -188 °C (-310 °F).
It reacts with water, forming hydrofluoric acid and hydrogen fluoride gas: HF + H2O → H⁺ + HF + OH⁻
The periodic table is a diagram that displays chemical elements in order of atomic number. The periodic table can explain how elements are categorized and how they are related to one another.
A chemical word for any element that does not have a metallic is a nonmetal. Gold, silver, copper, carbon, nitrogen, oxygen, fluorine, and iron are examples of nonmetals.
Helium (It is a Nonmetal) is the least reactive. Helium is the 2nd most abundant element in the universe at room temperature. Helium doesn’t react to anything. Because helium has an outer electron shell filled with electrons.
Why is fluorine more reactive than chlorine: Fluorine and chlorine are nonmetals belonging to the periodic table’s Group VIIA. As we proceed from top to bottom, the reactivity of the non-metallic elements in Group VIIA declines. Because fluorine’s atomic size is smaller than chlorine’s, the force of attraction between the nucleus and the valence electrons of the valence shell is stronger in fluorine, allowing it to obtain one electron more easily. Finally, fluorine has higher reactivity than chlorine.
