Metals and non-metals are two broad categories of
elements in the periodic table, distinguished by their
physical and chemical properties.

Metals and non-metals are two broad categories of
elements in the periodic table, distinguished by their
physical and chemical properties. 
Metals and Non-metals
State: Metals are generally in the solid
state at room temperature, except for
mercury (Hg), which is a liquid.
Hardness: Metals are typically hard, with
exceptions like lithium (Li), potassium (K),
and sodium (Na), which are relatively soft.
Luster: Metals exhibit metallic luster, which
gives them a shiny appearance.
Malleability: Metals can be hammered or
beaten into thin sheets without breaking.
Ductility: Metals can be drawn into wires,
making them ductile.

Physical Properties of Metals
Melting Point: Most metals have high melting points,
except for gallium (Ga) and cesium (Cs), which melt at
low temperatures.
Boiling Point: Metals generally have high boiling points.
Conductivity: Metals are excellent conductors of heat,
with silver (Ag) and copper (Cu) being the best
conductors. However, lead (Pb) and mercury (Hg) are
poor conductors.
Electrical Conductivity: Metals are good conductors of
electricity, with silver (Ag) and copper (Cu) being the
best.
Sonorous: Metals produce sound when beaten.

Physical Properties of Metals
State: Non-metals can exist as solids, liquids, or
gases at room temperature. Examples include
carbon (solid), sulfur (solid), bromine (liquid),
oxygen (gas), hydrogen (gas), and nitrogen (gas).
Hardness: Non-metals are generally soft, with
diamond being an exception as the hardest
natural substance.
Luster: Non-metals do not have metallic luster,
except for iodine crystals, which can appear shiny.
