Why is potassium more reactive than lithium and sodium?
Why is potassium more reactive than lithium and sodium?
Potassium metal is indeed more reactive than lithium metal, because potassium has a more loosely bound valence electron. In direct reactions, potassium reacts more violently than lithium.
Why K is more reactive than sodium?
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.
Why is K potassium more reactive than Li lithium )?
Lithium is smaller in size than potassium . so valence electrons are more tightly held in Li than K. Due to larger size of K the valence electrons are loosely held and easy to remove the electron from K. Hence K is more reactive.
Why is K more reactive?
Therefore, potassium has an additional shell of electrons and thus 8 more electrons. This extra shell of electrons shields the attractive force exerted on the outer electron by the nucleus. As a result, less energy is required to remove the outer electron of potassium and so it is more reactive.
Why is lithium more reactive?
Lithium is least reactive due to it’s small size. lithium is more reactive because lithium is a part of the group 1 alkali metals which are highly reactive and are never found in the pure form in nature.
What is more reactive lithium or sodium?
Reactivity 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 Na2O (sodium oxide). Lithium forms lithium oxide (Li2O).
Which is more metallic N or K?
Potassium has more energy levels than sodium, atom radius is also therefore more which makes potassium to lose electrons easily. Hence, making potassium more metallic than sodium.
Why is sodium more reactive than lithium GCSE?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.
| Element | Reaction with water |
|---|---|
| Sodium | Very quickly |
| Lithium | Quickly |
| Calcium | More slowly |
Is potassium stronger than lithium?
More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.
| Element | Reaction with water |
|---|---|
| Potassium | Violently |
| Sodium | Very quickly |
| Lithium | Quickly |
| Calcium | More slowly |
Which is more reactive K or FR?
Francium is a short-lived element but, it’s reactivity, even in cold water, is highly explosive and exothermic. It’s much more reactive than Potassium or other Alkali metal Elements. As we move down the list of these elements in Group 1 (1A) in the Periodic Table, the more reactive they become.
Which is more reactive K or Na explain giving chemical reaction?
Sodium atoms due to being smaller in size have high ionization energy and thus, it can’t lose electrons easily and is more stable and less reactive. Hence, from this it is clear that sodium is less reactive than potassium.
Is K more reactive than na?
