WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the reactivity of the alkali metals and halogens increases or decreases, put a pin in the middle of the periodic table and spin it anti-clockwise. WebApr 16, 2024 · In general, it seems to be a trend regarding the reactivity of alkaline metals with water which says that as you go down the group, they become more reactive towards water. But I'm curious about which factors explain this trend.

WebFeb 11, 2024 · The chemical reactivity of these elements increases down the group. Reactions with Oxygen (Air) The alkali metals tarnish in dry air. It is due to the formation of their oxides which in turn reacts with moisture to form hydroxides. Alkali metals burn vigorously in oxygen forming oxides. Lithium forms monoxide, \((Li_2O)\) sodium forms … WebGroup 1 elements need to lose one electron when they react. As you go down group one there are more energy shells so more distance between the outer electron and the nucleus This means the outer electron is less attracted to the nucleus going down group 1 Therefore it is easier to lose the outer electron as you go down the group daily tasks of a respiratory therapist

WebWhy does reactivity increase as you go down Group 1 metals? An atom is made in such a way that the nucleus with the positive charges (protons) is in the centre and the negative charge (electrons) are arranged in shells around it. All group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. WebGroup 1 elements have only one valence electron and they are highly reactive metals because they have to lose only this lone electron. Chemical reactivity of the metals would …
