Question

Name (a) a gaseous element, (b) a liquid metallic element and (c) a liquid nonmetallic element

Answer 1

• Elements are substances which are made up of similar kinds of atoms.
• We can not divide elements further by any other simple chemical processes.
• Elements can exist in different states solid, liquid and gas.
• a) Oxygen $\left(\mathrm{O}\right)$ is an example of a gaseous element since it exists in a gaseous state.
• b) Generally metals are hard and exist in the solid state but there is an exception, i.e.., mercury $\left(\mathrm{Hg}\right)$ which is a liquid metallic element.
• c) Bromine $\left(\mathrm{Br}\right)$ is a nonmetal which exists in a liquid state at room temperature.
