Simple Molecules vs Giant Structures
Types of Structures
Simple Covalent
According to Secondary Science 4 All "Simple covalent molecules. Simple molecular substances consist of molecules in which the atoms are joined by strong covalent bonds."
Example
Forces
Intermolecular
DescriptionIntermolecular forces are the forces that mediate the interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles.
Example
Intramolecular
An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules.
Example
Giant Covalent
According to bbc bitsize "Giant covalent structures contain very many atoms , each joined to adjacent atoms by covalent bonds . The atoms are usually arranged into giant regular lattices - extremely strong structures because of the many bonds involved."
Example
Diamond & Sand
Graphite
Fullerenes
Carbon Nanotubes
Mettalic
According to bbc bitesize "In metals, the electrons leave the outer shells of metal atoms , forming positive metal ions and a 'sea' of delocalised electrons. The structure of a solid metal consists of closely packed metal ions, arranged in a regular way to form a metallic lattice structure."
Example
Bonds
Covalent Bonds
Is a chemical bond which involves the sharing of electrons
Example
Ionic Bonds
Is the transfer of valence electrons between atoms
Example
Properties
Delocalised
Delocalised electrons are spread across more than one atom. Usually electrons in materials are bound to one atom, and atoms are held together by the interactions of the charges on different atoms.
