Solid State Flashcards
Learn about all the solids
is a collection of atoms or molecules that are held together so that, under constant conditions, they maintain a definite shape and size or volume.
Solid
Types of solid
Crystalline Solids
Amorphous Solids
is asolid material whose constituents (such asatoms,molecules, orions) are arranged in a highly ordered.
Crystalline solid
are composed of positively and negatively chargedions held together by an ionic bond.
Iomic solids
Have high melting poimt
Ionic solid
Individualmolecules are composed ofatomsheld together by strong covalent bond.
Molecular solids
tend to melt at relatively low temperatures.
Molecular solids
are solids that are composed of atoms
Atomic solids
Properties of atomic solid
Network Solids
Metallic Solids
A continuous network of covalent bonds hold together all the atoms.
Network solids
Composed of metallic atoms
are nondirectional
Electron sea model
Metallic solids
ability to conduct heat and electricity
Electrical and thermal conductivity
ability to hammer asolid into a sheet without breaking it
Malleability
ability to stretch a solid to form a wire.
Ductility
Properties of solid
Non-directionality of bond in metallic solids
