The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen.

The reactivity of alkali metals increases down the group due to the increasing atomic radius and decreasing ionisation energy of the elements.

9 янв. 2020 г. · The reactivity of alkali metals is due to their electropositivity. Electropositivity increases down the group of alkali metals, thus the ...

30 июн. 2023 г. · Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. Не найдено: down | Нужно включить: down

15 июл. 2024 г. · The reactivity of the Group 1 metals increases as you go down the group; When a Group 1 element reacts, its atoms only need to lose the 1 ...

Reactivity increases down the group. This is because the outer electron in each atom is further away from the nucleus as you go down the group.

The reactivity of alkali metals increases on moving down the Group, Francium is the most reactive alkali metal followed by Caesium, Potassium, Sodium, and ...

Therefore, as you go down the group the outermost electron becomes easier to lose and the reactivity increases as you go down the group. GCSE Chemistry - Group ...
