The Most Reactive Metal Is

Q. The most reactive metal is _____ (a) Sodium (b) Magnesium   

(c) Potassium  (d) Calcium

Answer: The following factors contribute to potassium’s high reactivity:

Because potassium metal has more shells than sodium, it is easier to remove one electron from its outermost orbital.

Potassium has a very low ionization enthalpy.

It is the metal with the highest electropositivity, making it the most reactive.

Because the reactions are highly exothermic, the hydrogen gas produced as a byproduct ignites.

In a reactivity series, the element with the highest reactivity is at the top, followed by the least reactive. Higher reactivity metals tend to lose electrons and create positive ions more frequently.

Potassium is a soft, silvery-white element having one extra electron than argon, which is recognised for its exceptional stability. The “extra” electron in potassium is quickly removed, resulting in the considerably more stable cation, K+. We can observe the elemental potassium only after the atom loses this electron. This elemental potassium is quite similar to sodium which is another highly reactive alkali metal in the group. Because of this high reactivity trait the scientists keep working with it in top physical form as they escape for their life from the subsequent explosion and flames. If potassium were a human, it would be required by a court to attend an anger management class.

Potassium has a variety of uses. This pump is a large transmembrane protein that uses ATP to create a concentration and charge gradient across a cell’s membrane by selectively “pumping” K+ and Na+ ions from one side to the other. Because they are used to power a variety of cellular functions, these gradients are vital to life.
