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 converted to ionic form more readily than sodium. Hence, potassium is more reactive than sodium.

on moving down the group in the alkali metals, the size of the atom increases and the effect of the nuclear charge gets decreased. Due to this factors, the electron of potassium which is located outer gets lost easily as compared to Na. therefore, potassium reacts higher than Na.

Explain the significance of sodium, potassium, magnesium and calcium in biological fluids.

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.

Why is cyclopropane more reactive than propane?

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...

Explain why : (a) H2S is more acidic than H2O. (b) Two S – O bonds in SO2 are identical. (c) SF6 is inert and stable but SF4 is reactive.

[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...

(i) Interhalogen compounds are more reactive than halogens except F2. Why ?

(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.
