Bonding

Primary bonding

secondary bonding

Metallic Bonds

Ionic Bonds

sharing of variable number of electrons by a variable number of atoms.

force of attraction between the positive metal ion and "sea of electron"formed between atoms of metal.

solid in state except mercury

Insoluble in all solvonts

High boiling and melting point as a result of giant mettallic structure

malleable and ductile

conducts electricity in the solid and molten state

what does covalent means?

there con't conduct electricity

the number of bond determine the number of electrons

if forms because the electrostatic all raction between the nuclei of the atom and shared electrons

non-metals react with non- metals and there share electrons

there is no charges because electrons are shared not transferred

Properties

Hydrogen bonding

found in most of materials, but overshadowed by the strength of primary bonding.

weak in nature

caused by the attractions between electron-rich region of one molecules and electron-poor region of another.

exist between some molecules that have hydrogen as one of the constituents
