Explain why Sodium is less reactive than Potassium?

Thus, in potassium, the outermost electron is better shielded from the attractive force of the nucleus. It follows, therefore, that this outermost electron is more easily lost than it is in sodium, so potassium can be...

Solution: Significance of sodium and potassium in biological fluids: K+ and Na+ cations are present in the red blood cells. The ratio of K+ to Na+ ions in mammals such as human beings, rabbits, rats and horses is 7:1.

In Cyclopropane, bond angle is 60o which is much less compared to the normal tetrahedral bond angle of 109.5o for sp3 hybridized carbon. Therefore, the molecule is very much strained...

[Hint : Because it have polymeric structure consisting chains of P4 tetrahedra, hence denser than white P while red P is not having angular strain as in white P, hence...

[Hint : (iii) Because six F atoms protect the sulphur atom from attack by any reagent due to steric hindrance but four F atoms in SF4 cannot offer much steric hindrance, hence...

ICl is more reactive than I2 because I−Cl bond in ICl is weaker than I−I bond in I2.

(i) Because X-X bond in interhalogens is weaker than X-X bond in halogens except for F-F bond. (ii) ClF3 is used for the production of UF6.

The two N atoms in N2 are bonded to each other by very strong triple covalent bonds. The bond dissociation energy of this bond is very high. As a result,...

ICl is more reactive than I2 because I−Cl bond in ICl is weaker than I−I bond in I2.

(c) Assertion is correct, reason is incorrect
