Calamine is an ore of :
Correct answer: B. Zn
- A. Hg
- B. Zn
- C. Cd
- D. Ca
Explanation
Calamine is a mineral that is a significant source of zinc. It is primarily composed of zinc carbonate (ZnCO3) along with variable amounts of other minerals like smithsonite (another form of zinc carbonate) and various zinc silicates. Zinc carbonate minerals like calamine are important zinc ores and are processed to extract zinc metal.Zinc is an essential element used in various industrial applications, including galvanizing (coating with a layer of zinc for corrosion protection), alloying with other metals, and in the production of batteries and various products like rubber, paint, and ceramics.Option B (Zn) is the correct answer as calamine is a significant source of zinc, not mercury (Option A), cadmium (Option C), or calcium (Option D).

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
