Lead is unaffected by water because:
Of poor shielding effect
Of its metallic nature
Of formation of a protective oxide film
Of large covalent radius
Lead is unaffected by water because of formation of a protective oxide film.
Present a comparative account of the alkali and alkaline earth metals with respect to the following charactieristics.
(i) Tendency to form ionic / covalent compounds
(ii) Nature fo oxides and their solubility in water
(iii) Formation of oxosalts
(iv) Solubility of oxosalts.
(v) Thermal stability of oxosalts.
