Answer :
Metals: copper, aluminium, mercury, sodium
Non-metals: sulphur, oxygen, nitrogen, chlorine
Metalloids: silicon, germanium
Metals, non-metals, and metalloids are categories of elements based on their properties, particularly their conductivity, lustre, and chemical behavior.
Metals:
Copper (Cu): Copper is a ductile metal with high electrical and thermal conductivity. It's commonly used in electrical wiring, plumbing, and various industrial applications.
Aluminium (Al): Aluminium is a lightweight metal with good conductivity and high strength-to-weight ratio. It finds extensive use in aerospace, construction, and packaging industries.
Sodium (Na): Sodium is a highly reactive metal that is soft and easily cut. It's commonly found in salts and is essential for biological processes.
Non-metals:
Sulphur (S): Sulphur is a non-metal with distinct yellow color and is commonly found in nature in its elemental form as well as in various compounds. It's used in the production of sulfuric acid, fertilizers, and in vulcanization of rubber.
Oxygen (O): Oxygen is a non-metal gas essential for respiration and combustion. It's the most abundant element in the Earth's crust and plays a crucial role in various chemical processes.
Nitrogen (N): Nitrogen is a non-metal gas that makes up a significant portion of the Earth's atmosphere. It's essential for life and is commonly used in the production of fertilizers and various industrial processes.
Chlorine (Cl): Chlorine is a non-metal gas that is highly reactive. It's commonly used in disinfectants, bleaches, and as a reagent in chemical synthesis.
Metalloids:
Silicon (Si): Silicon is a metalloid with both metal-like and non-metallic properties. It's a crucial component in semiconductor devices, as well as being abundant in the Earth's crust.
Germanium (Ge): Germanium is a metalloid used in semiconductors and fiber-optic systems.
Mercury (Hg): Mercury is a metalloid that is liquid at room temperature. It's highly toxic and historically has been used in thermometers, barometers, and various industrial processes.
