Protons have a +1 charge and electrons have a -1 charge. The overall charge on an atom is 0, therefore there must be an equal number of protons and electrons in an atom so that the charges cancel out. So ...

The molecular geometry deals with the position of the nucleus of the different atoms in the molecule whereas the electron geometry deals with the position of the orbitals. Electron geometry is specific fo...

(Using a diagram of energy changes) The simplest way of thinking about it is that exothermic reactions release energy, such as heat, to the surroundings whereas endothermic reactions absorb energy from th...

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...
