Explain the difference between hybrid atomic orbitals in valence bond theory and lcao molecular orbitals in molecular orbital theory

They really have distinctive forecasts now and again. For example, valence bond hypothesis predicts no unpaired electrons in sub-atomic oxygen, while sub-atomic orbital hypothesis predicts two unpaired electrons in the 2 π ∗ orbitals. 
The Molecular orbital hypothesis can be checked for this situation since sub-atomic oxygen is paramagnetic. VB hypothesis is sensibly great at giving subjective data about the states of particles, yet MO hypothesis gives more data about vitality levels, bond qualities, and so on.

Ibelieve your answer is true 

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
