Muhtasari / Summary: Ionic, covalent, and metallic bonding with properties.

Ionic bonding: transfer of electrons between metal and non-metal, forming ions held by electrostatic attraction (e.g. NaCl). Properties: high melting point, conducts electricity when molten/dissolved. Covalent bonding: sharing of electrons between non-metals (e.g. H₂O, CH₄). Properties: low melting point, poor conductor. Metallic bonding: sea of delocalised electrons around positive ion lattice – explains conductivity and malleability of metals.
