Physical properties
1) Physical state – Metals are solids at room temperature e.g. sodium, aluminum ,potassium, magnesium. There are exception to this. Mercury and gallium are metals but they are in liquid state at room temperature.
2) Luster – Metals have a shining surface called luster when freshly prepared. They have a quality of reflecting light from their surface and they can be polished e.g. metals like gold, silver, copper show this property.
3) Malleability – Metals can be beaten into thin sheets. This property is called malleability. Due to this property, metals can be rolled into sheets e.g. aluminum, copper, zinc can be beaten into sheets.
4) Ductility – Metals can be drawn into thin wires. This property is called ductility. For example, 100 grams of silver can be drawn into a thin wire about 200 meters long.
5) Hardness – Metals are generally hard e.g. iron, cobalt, nickel. There are few exceptions to this. Sodium and potassium are soft and they can be cut with a knife.
Chemical properties of metals
1) Electron configuration – Metals usually have 1 to 3 electrons in the outermost shell of their atom. For example, sodium, magnesium and aluminum have 1, 2 and 3
electrons respectively in the outermost shell of their atom.
2) Valency – Metal atoms can lose 1 to 3 electrons in their outermost shell and show valencies1 to 3.
