Question

Which of the following metals exist in their native state in nature? $1)\mathrm{Cu}2)\mathrm{Au}3)\mathrm{Zn}4)\mathrm{Ag}$

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (ii) and (iv)
• D. (iii) and (iv)

Answer 1

The correct option is C

(ii) and (iv)

Explanation for correct option:

C. (ii) and (iv)

Metals:

• A metal is a class of substance that has high electrical/thermal conductivity.
• Metals are usually malleable as well as ductile in nature.
• Examples of metals are Sodium$\left(\mathrm{Na}\right)$, Lithium$\left(\mathrm{Li}\right)$, and Potassium$\left(\mathrm{K}\right)$.

Uses of metals:

• Metals such as gold or silver are used in making jewelry or ornaments.
• Metals such as iron or steel are used for construction purposes.
• Utensils are made up of aluminum and steel.

Out of the given metals, the metals that exist in their native state in nature are Silver and Gold.

Only two metals, gold, and platinum are found principally in their native state, and in both cases, the native metals are the primary ore minerals. Native silver occurs as elongated dendritic coatings and it is comparatively less reactive than other metals.

Explanation for incorrect options:

Silver and gold exist in their native state. Thus options A, B, and D are incorrect.

Hence, the correct option is C i.e. (ii) and (iv).
