Shapes of molecules and ions
WebbThere are four basic types of crystal: ionic – a lattice formed by positively and negatively-charged ions. metallic – a regular lattice of positively-charged metal ions surrounded by a ‘sea’ of delocalized electrons. macromolecular (giant covalent) – a regular lattice of atoms held together by covalent bonds. molecular (simple covalent) – a regular lattice of … WebbSHAPES OF SIMPLE MOLECULES AND IONS Electron pair repulsion theory This is used to predict the shapes of simple molecules and ions by considering the repulsions between pairs of electrons (lone pair and bond pair) within the molecule.
