Is potassium more reactive than rubidium? - Answers
WitrynaAnswer: Potassium is much more reactive than 3rd Period sodium. Because its valence electron is farther removed from the nuclear core, the metal is a much stronger reducing agent. Sodium can be safely destroyed by ethyl alcohol…the attempt to do so with potassium will result in flames…and other m... Witryna30 lis 2024 · Silicate coatings are alkali metal silicates that are made from naturally occurring materials such as sand and alkali.Alkali metal silicates are derived from a combination of silica (SiO 2) and a carbonate of lithium, sodium or potassium to produce a silicate (SiO 2 /Na 2 O). Depending on their formulation, these remarkable … charlie cards boston
Difference Between Sodium and Potassium
WitrynaPotassium and sodium react violently with dilute acids, producing sparks and … Witryna6 cze 2024 · As potassium is larger than sodium, potassium’s valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium’s valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive. WitrynaReactivity of Group 1 and 2 elements increases as you go down the periodic table. So sodium is more reactive than lithium. Sodium will react with oxygen forming $\ce{Na2O}$ (sodium oxide). Lithium forms lithium oxide $\ce{(Li2O)}$. Basically, there are general trends (reactivity with acids, air, etc.) down a group or along a period. charlie card refill station
