example of elements and compound and thier reason
Answer (1)
1. Element Example: Oxygen (O) Reason: Oxygen is made up of only one type of atom — oxygen atoms. It cannot be broken down into a simpler substance by physical or chemical means. Elements are the basic building blocks of matter. 2. Compound Example: Water (H₂O) Reason: Water is made of two different elements — hydrogen and oxygen — chemically combined in a fixed ratio (2 atoms of hydrogen for every 1 atom of oxygen). Compounds can be separated into their elements only through chemical reactions, not by physical means. In simple terms: An element = one kind of atom only. A compound = two or more different atoms chemically joined together[tex].[/tex]
