What is the most reactive element from Li and Na and K?
potassium
All the group 1 metals are reactive, but they get more reactive as you go down the group, so potassium is more reactive than sodium, which is more reactive than lithium. This can be explained by looking at the electronic structure of the atoms: In order to react, the metal needs to lose an electron.
Which is the more reactive metal Li or Na?
Sodium is more reactive than lithium because sodium is larger in size. Outermost electrons are less tightly held in sodium than in lithium. As a result, sodium loses its outermost electron more easily than lithium. Hence, it is more reactive than lithium.
Which metal is more reactive Li or K?
The potassium-lithium issue explained. 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.
Is K the most reactive metal?
– Potassium metal has more number of shells compared to sodium and thus it becomes easy to remove one electron from its outermost orbital ( less ionization enthalpy). – So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.
Is lithium the most reactive metal?
So, the correct answer is option D. Note- On the periodic table the most reactive element is the francium. But Francium is a laboratory-produced element and only minute amounts have been made, so the most reactive metal is cesium for all practical purposes.
Why Li is most reactive?
Reactivity. Lithium is part of the Group 1 Alkali Metals, which are highly reactive and are never found in their pure form in nature. This is due to their electron configuration, in that they have a single valence electron (Figure 1) which is very easily given up in order to create bonds and form compounds.
Why Na is more reactive than Li?
Sodium is more reactive than lithium because sodium is larger in size. Outermost electrons are less tightly held in sodium than in lithium. As a result sodium loses its outermost electron more easily than lithium. Hence it is more reactive than lithium.
What is more reactive Li or be?
Answer: Beryllium (Be) is less reactive because it is to the right of lithium (Li) in the period.
Why is K most reactive?
Answer: Potassium (K) is more reactive because it is further down in Group 1 than sodium (Na).
Why is Li higher than K on activity series?
The reason that lithium is on the top of the activity series is due to its behavior in aqueous reactions with water and acid. Due to the lithium atom’s very small size (only two energy levels), the lithium ion interacts well with water forming ion-dipole interactions.
Why is lithium least reactive?
Lithium is the least reactive because it is the one with the least electrons. That means the electrons are closer to the nucleus and therefore more attracted to it.
Why lithium reacts less vigorously than sodium?
More electronegative. Complete answer: Sodium react with water more vigorously than lithium because by the following reasons; Sodium is greater than lithium in size because as we go down the group size of alkali metal increases due to an extra shell.
Which one is more reactive Na or K and why?
Is lithium a reactive metal?
Chemical properties In many of its properties, lithium exhibits the same characteristics as do the more common alkali metals sodium and potassium. Thus, lithium, which floats on water, is highly reactive with it and forms strong hydroxide solutions, yielding lithium hydroxide (LiOH) and hydrogen gas.
Where is lithium on the reactivity series?
top
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 |
|---|---|
| Lithium | Quickly |
| Calcium | More slowly |
Why Is lithium the most reactive metal?
How is lithium less reactive?
Why does sodium react faster than lithium?
On moving down the group, the electropositive nature increases; hence sodium is more electropositive than lithium and also the size of sodium is greater than lithium. So Sodium reacts more vigorously with water than Lithium.
Which is more reactive lithium or potassium?
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 |
