Solution

Answer :

(a) The oxide $E_{2} O$ is basic in nature because it turns red litmus paper blue.

(b) The element E is a metal because metal oxides are basic in nature.

(c) Sodium (Na) is an element like E. It forms the oxide $N a_{2} O$ on reacting with oxygen, which turns red litmus paper blue.
