A transition metal is defined as an element that forms a stable ion with incompletely filled d orbitals. Scandium forms a 3+ ion with no electrons in its d orbitals and zinc forms a 3+ ion with completely...
In nature, when 2 elements react, energy is taken in to break bonds and energy is given out to form new bonds. The net change in heat energy during a reaction at constant pressure is called the enthalpy c...
Kekulé's model of benzene is that it has 3 double bonds, in a ring of 6 carbons.One - Benzene isn't very reactive, so if Kekulé's model were to be correct, there would be 3 double bonds in benzene, ...
The p orbitals on each carbon atom in benzene overlapThere is delocalisation of electrons in the ring (not 3 localised C==C double bonds)This makes benzene more thermodynamically stable than predictedIt t...
