The Electronic Structure of Atoms - Assignment ExampleAccording to this principle, electron are filled in shells of the blood cell that they get most stabilized. The electron are filled in increasing order of orbitals energy.Hunds rule states that if orbitals of equal energy are available to electrons, so the electrons prefer to fill them in unpaired form before pairing. It gives maximum positive spin number to electrons.There are six electron in carbon. Two are birth in 1s orbital, 2s contain two electron and there are two unpaired electrons in 2p orbital. The energy difference between 2s and 2p orbitals is small due to which matchless electron from 2s is shifted to third empty 2p orbital and then carbon makes four bonds in its compounds.The Pauli Exclusion Principle states that no two electron in an atom can have all same quantum number values. If there are two electron with same principle quantum number, azimuthal quantum and magnetic quantum number then they will have opposit e spin quantum numbers. They will be paired with opposite spins.4s is orbital is filled first of all. Because n+l value for 4s is 4=1=4, while for 3d, it is 3+2=5. Here n+l rule is followed according to which, orbitals with lower value of n+l are filled firstly and they are lower in
