Elements can be classified as metals and non-metals based on their physical and chemical properties. Metals exhibit characteristics such as metallic luster, malleability, ductility, and good conductivity of heat and electricity, while non-metals display the opposite properties. The chapter extensively discusses the reactivity series of metals, their extraction, and prevention of corrosion, along with distinguishing features of ionic compounds.

Elements can be classified as metals and non-metals.
Metals are lustrous, malleable, ductile, and good conductors of heat and electricity.
Non-metals are neither malleable nor ductile and are generally poor conductors.
The shiny appearance of metals in their pure state.
The ability of a metal to be beaten into thin sheets.
The ability of a metal to be drawn into thin wires.
Metal oxides that exhibit both basic and acidic properties, such as aluminum oxide.
A list of metals arranged in the order of their decreasing activities.
Compounds formed by the transfer of electrons from metals to non-metals, resulting in the formation of positively and negatively charged ions.
