BDE (Bond dissociation energy) is the energy require to split the chemical bond in half. This would lead to two radicals through homolysis. Binding energy is a bit more vague in my opinion. For atoms it means disassembling the atom into free electrons and a nucleus. In chemistry it is the average energy required to break all bonds in a molecule.
