Question

Which of the following is most abundant metal on the earth's crust?

• A. Iron
• B. Aluminium
• C. Calcium
• D. Oxygen

Answer 1

The correct option is B

Aluminium

Metal is any of a group of materials which have high electrical and thermal conductivity, as well as malleability, ductility, and high light reflection.

Explanation for the correct option B:

Aluminum is never found in its metallic form in nature due to its chemical reactivity, but its compounds can be found in different degrees in almost all minerals, flora, and animals.

Aluminium $\left(\mathrm{Al}\right)$ is the most abundant metal on the Earth's crust.

Explanation for the incorrect options

A)Iron$\left(\mathrm{Fe}\right)$ is the second most abundant metal in the Earth's crust.

C)Calcium$\left(\mathrm{Ca}\right)$ is $3.63\%$ abundant on the Earth's crust.

D)Oxygen$\left({\mathrm{O}}_2\right)$ is a non-metal.

Hence, option(b) is the correct answer. Aluminium$\left(\mathrm{Al}\right)$ is the most abundant metal on the Earth's crust.
