Types of bonding

Metallic Bonds
Metallic bonds are very brittle and hard, they have high melting points and boiling points and also have a very high conductivity of heat and electricity. Metallic bonds are also lustrous, malleable and ductile

Structure: Metallic bonds are held together in 3D lattices through positive ions that are attracted to a delocalized sea of electrons. These mobile delocalized electrons transfer charge and heat energy. They’re ability to rapidly response to electric fields and transmit kinetic energy allows them to be good conductors of heat and electricity. The strong metallic bonds between metals give it its high melting/boiling points as well as relatively high density. Furthermore the individual atoms that are not held to any specific type of atom allow them to slip easily past one another making them extremely malleable mad ductile.

Ionic Bonds
Ionic bonds are very hard and brittle, they have high melting and boiling points. However they cannot conduct electricity in their solid state WITH the only exception of doing so in their LIQUID state.

Structure: Ionic bonds are positive ions held together in fixed proportions with negative ions in a 3 dimensional lattice through a STRONG ELECTRICAL FORCE. This electrical force is extremely strong making the structure very hard. Because the ions are so tightly bonded they are not free to move and carry an electric current. However in a liquid form they are allowed to conduct electricity since the particles are now free to move.

Covalent Network (BIG AND STRONG)
Covalent network are very hard a brittle, they have very high melting and boiling points also however being a covalent bond, they cannot conduct heat or electricity whatsoever.

Structure: Covalent networks bond with other non metals
