Nonmetals are gases (Cl, Ar, N...), liquids (Br) or solids brittle and with a very low hardness (S, P, Se..).

Physical properties of a metal refer to characteristics such as density, conductance of heat and electricity, malleability, ductility, and luster. These properties are inherent to the metal and help distinguish it from other materials.
The method used to extract a metal is determined by factors such as the reactivity of the metal, its abundance in the Earth's crust, and the cost-effectiveness of the extraction process. Additionally, the physical and chemical properties of the ore from which the metal is extracted also play a role in selecting the extraction method.
One physical test that can be used to distinguish between a metal element and a non-metal element is the ability to conduct electricity. Metals generally conduct electricity well, whereas non-metals are poor conductors. Another test is the luster or appearance - metals are usually shiny and have a metallic luster, while non-metals are dull in appearance.
Only one of these occurs naturally.
The stroking method involves repeatedly stroking a magnet in the same direction along a piece of metal to align the domains of the metal and magnetize it. This process helps induce magnetism in the metal by aligning its domains with the magnetic field of the magnet. It is a simple and effective technique to create temporary magnets.
Iron is a magnetic metal, aluminium is not.So, a simple method is to use a magnet for this separation.Magnetic separation is frequently used to extract iron from wastes.
what is the physical property of a non-metal
Shiny metal is a physical property because it can be observed without changing the chemical composition of the metal. It is a characteristic related to how light interacts with the surface of the metal.
