Metals and Non-metals Physical and Chemical Properties …
Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. 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, so they can be cut using knife.
