Question

Strike through the odd one out. Give reasons for your choice.

Zinc, iron, copper, mercury, aluminium

Answer 1

• Zinc$\left(\mathrm{Zn}\right)$ is bluish-white colored brittle metal.
• Iron$\left(\mathrm{Fe}\right)$ is a silvery-grey lustrous metal.
• Copper$\left(\mathrm{Cu}\right)$ is reddish-brown colored lustrous metal.
• Mercury$\left(\mathrm{Hg}\right)$ is a silvery metal with a lustrous shine.
• Aluminium$\left(\mathrm{Al}\right)$ is a silvery-white metal.
• So, all the given elements are metals but there is one exception.
• Generally, all the metals are found in solid-state except Mercury and Gallium which are liquids at room temperature.

Hence, the odd one out is Mercury
