Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals
