most reactive groups on the periodic table

Various chemicals can be formed by the reaction of halogens with other elements and compounds. With the presence of a small amount of water, fluorine can react with its glass container, forming silicon tetrafluoride, or SiF 4. It can even react with materials that are considered inert, like glass. In fact, it can be argued that it’s the most reactive naturally-occurring element that we know of. However, as the atomic radius increases, the stability of the diatomic bonds decreases.įluorine is the most reactive element of all halogens. As elements, halogens exist as diatomic molecules (molecules made up of two atoms). Therefore, higher electronegativity means stronger reactivity. All halogens are highly electronegative due to the high effective nuclear charge of the elements.Įlectronegativity measures the ability or tendency of an atom to attract electrons in either shared covalent bonds or in ionic bonds. Additionally, they all have an ‘ s’ (spherical shape) and a ‘ p’ (dumbbell shape) orbital in the outermost shell. Halogens have seven valence electrons in their outermost energy level, which can be denoted by ns 2np 5. This is mainly because of their atomic structures and electron configuration. Just like other groups in the periodic table of elements, the six elements in column 17 have similar chemical and physical properties. What Are the General Properties of Halogens?
