The main factor influencing a given compound's state is the strength of intermolecular forces - those need to be larger than the thermal energy for a compound to be solid/liquid. For CO2 the only type of ...
Benzene consists of six carbon atoms in a hexagonal ring, all of which are sp^2 hybridised. This allows the perpendicularly oriented 'p' orbital of each carbon to overlap laterally all around the ring. Th...
Ionisation energy is defined as the energy required to remove an electron from a gaseous atom or ion. As we descend down a periodic group we must think about how the atomic radius...
The colour of light is determined by its wavelength. White light is made up of electromagnetic radiation (photons) that spans the range 400nm - 700nm, the visible part of the E.M. spectrum. When white lig...
When an ionic compound is a solid, the ions in the ionic lattice are held together by ionic bonds. Due to this, the ions are not free to move around and so cannot carry a charge. When the ionic compound i...
