Energy of the electron in Hydrogen atom is given by: (1) E n = 131.38/ n 2 x kj mol -1 (2) E n = 131.33/n xkj mol -1 (3) E n = 1313.3/ n 2 x kj mol
When a molecule is shown by two or more nearly equal structures, which vary in the arrangement of electrons, then the molecule is said to exhibit resonance.
The statements: (1) In filling a group of orbitals of equal energy, it is energetically preferable to assign electrons to empty orbitals rather than pair them into a particular o
