Why is Li more reactive than K?

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.

Is potassium 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.

Is lithium more reactive?

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

Is Li more reactive than na?

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).

Is lithium reactive?

Lithium is pretty; a shiney silvery alkali metal. It is so soft it can be cut with scissors and it’s so light that it floats on water. But it’s also extremely reactive so it doesn’t stay shiney or silvery very long. For this reason, it is never found “in the wild” in its pure elemental form (on earth).

Does lithium have a higher melting point than potassium?

The alkali metals also have low densities . They are low enough for the first three (lithium, sodium and potassium) to float on water….Example.

Element	Melting point
Lithium, Li	180°C
Sodium, Na	98°C
Potassium, K	63°C
Rubidium, Rb	39°C

Does lithium displace potassium?

The topmost five elements, form lithium to sodium are known as very active metals; hence they react with cold water to produce the hydroxide and hydrogen gas….Reactivity Series of metals Chart.

Metal	Potassium
Symbol	K
Reactivity	Displaces H2 gas from water, steam and acids and forms hydroxides.
Extraction	Electrolysis

Why is lithium so 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.

Is lithium the most reactive metal?

Is lithium reactive or nonreactive?

Is lithium water reactive?

Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic.
