ratio, whereas mixtures are physically combined and can vary in composition. Q2: Can compounds be broken down into elements? A: Yes, compounds can be broken down into their constituent elements only through chemical reactions like electrolysis or heating. Unders
tom Cannot be broken down into simpler substances by chemical reactions Exist naturally or synthetically Represented by chemical symbols (e.g., H for Hydrogen, O for Oxygen) Examples of elements: Gold (Au) Carbon (C) Oxygen (O) Iron (Fe) What Are Compounds? Compounds are pure substances formed when
operties. It categorizes elements into groups such as: Metals: Good conductors, malleable, ductile, tend to lose electrons during reactions. Non-metals: Poor conductors, brittle, tend to gain electrons. Metalloids: Have properties intermediate between metal
