Question

Name one each: The most abundant metal and non-metal in the earth's crust.

Answer 1

Most abundant metal:

• The most abundant metal is silvery-white in appearance and is a good conductor of heat and electricity.
• The name of that metal is Aluminium $\left(\mathrm{Al}\right)$.
• It is about $8\%$ of the earth's crust and is a lightweight metal.

Most abundant non-metal:

• The most abundant non-metal is the most important element for sustaining human life.
• It is mainly found in the form of oxides.
• The name of that non-metal is Oxygen$\left(O_2\right)$.
• It is found around $46\%$ of the earth's crust.

Therefore, Aluminium$\left(\mathrm{Al}\right)$ is the most abundant metal and Oxygen$\mathbf{\left(}{\mathbf{O}}_{\mathbf{2}}\mathbf{\right)}$ is the most abundant non-metal found in the earth's crust.
