potassium rubidium reactive

is potassium more reactive than rubidium - aratea.org

"@type": "Article", Experiments show that Rubidium is indeed more reactive than potassium and Caesium is even more reactive than Rubidium. This reagent reacts with propene to form the compound allylpotassium (KCH 2 CHCH 2). Down group 1 the reaction gets faster and more violent as the alkali metal gets more reactive.

1997-1-1  Potassium and rubidium are both radioactive but the half-lives of their radioisotopes are so long that the atomic weight does not vary significantly from this cause. The large size and low ionization energies of the alkali metals compared with all other elements have already been noted ( pp. 23–5 ) and this confers on the elements their characteristic properties.

Rubidium - an overview ScienceDirect Topics

Rubidium is a typical but very reactive member of the series of alkali metals. It is appreciably more reactive than potassium, but less so than caesium, and so would be expected to react more violently with those materials that are hazardous with potassium or sodium. Rubidium ignites on exposure to air or dry oxygen, largely forming the oxide.

2012-5-9  Similarly, atoms of potassium (K in the table) are larger, and so more reactive, than atoms of sodium. It follows that elements below potassium in the table should be more reactive than potassium is. Experiments show that Rubidium is indeed more reactive than potassium and Caesium is even more reactive than Rubidium.
