✌✌

If the chemical formula of oxide of an element is X2O3. Then it means that element has tendency to loose 3 electrons from valence shell. CHLORINE has tendency to gain one electron. 3 electrons lost by the element will gain by 3 chlorine atoms.So it will form a compound with chlorine having formula ➡️ XCl3.⬅️
