WebAug 21, 2024 · Reactivity of Elements (d ecreases down the group) The reactivities of the halogens decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size with an increase of electronic energy levels. This lessens the attraction for valence electrons of other atoms, decreasing reactivity. WebAug 15, 2024 · Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals. All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. Group 2: Chemical Properties of Alkali Earth Metals

WebJan 5, 2024 · This willingness and ease of losing an electron to reach a state of equilibrium is known as high reactivity. In fact, reactivity in chemistry is defined by the number of electrons in the outermost shell. Noble gases (elements like neon and helium) are very unreactive because their outermost electron shells are full.
