Question

Name the metal which is the most abundant in earth's crust?

Answer 1

• The earth's crust contains Oxygen (${\mathrm{O}}_2$), Silicon ($\mathrm{Si}$), Aluminum ($\mathrm{Al}$), Iron ($\mathrm{Fe}$), and other elements.

• The earth's crust contains: $40.6\%$ Oxygen (${\mathrm{O}}_2$), $27.7\%$ Silicon ($\mathrm{Si}$), $8.09\%$ Aluminum ($\mathrm{Al}$), and $5\%$ Iron ($\mathrm{Fe}$).
• Among Oxygen (${\mathrm{O}}_2$), Silicon ($\mathrm{Si}$), Aluminum ($\mathrm{Al}$), and Iron ($\mathrm{Fe}$), Oxygen (${\mathrm{O}}_2$) and Silicon ($\mathrm{Si}$) are non-metals, while Aluminum ($\mathrm{Al}$) and Iron ($\mathrm{Fe}$) are the metals. So, Aluminum ($\mathrm{Al}$) is the most abundant metal in the earth's crust.
