As 1s orbital is the least energy orbital and nearest to the nucleus electron enters in 1s orbital first. The orbital diagram is formed using Hund’s rule and Pauli Exclusion Principle. Lead excited state electronic configuration Ground state lead orbital diagram Excited state electronic configuration of Lead can be drawn below. Due to the gain of this energy, an electron from 6s orbital jump to 6pz orbital. When the Pb atom gets excited then, it absorbs energy. In the ground state, the Pb atom contains two unpaired electrons. This arrangement is of higher energy level. Lead ground state electronic configuration The excited state of lead electron configuration Ground state electronic configuration of Lead can be depicted below. The ground state is the most stable arrangement. Two electrons in 6p orbital Ground state lead electron configuration.Lead unabbreviated electron configuration contains 82 electrons which can be distributed in a different orbital as below. Lead unabbreviated electron configuration can be written as below.ġs 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 2 4f 14 5d 10 6p 2 Lead unabbreviated electron configuration Next, two electrons in the 6s orbital, fourteen electrons in the 4f orbital, ten electrons in the 5d orbital, and two electrons in the 6p orbital. First, 54 electrons are represented by writing the Xenon gas symbol. The electronic configuration notation of Lead consists of a total of 82 electrons. The electronic configuration of Lead can be shown below. The Lead electronic configuration diagram Lead electron configuration notation After 4f, 5d, and 6p orbitals are filled.Next to 6s, electrons enter the 4f orbital having a maximum capacity of holding fourteen electrons.In the same way 4p, 5s, 4d, 5p, 6s orbital are filled.After 4s, electrons enter the 3d orbital, which can hold a maximum of ten electrons.In the same way, after 3s, 3p, and 4s orbital filled.After the 2p orbital, the 3s orbital is filled, which can hold a maximum of two electrons.After this, the electron enters in 2p orbital, which holds a maximum of six electrons.Next to this 2s orbital which can hold a maximum of two electrons, is filled. 1s orbital having the least energy and maximum capacity of two electrons, is filled first.The electronic configuration of Lead can be represented by a diagram as shown below. Thus final configuration of lead can be written asġs 2 2s 2 2p 6 3s 2 3p 6 4s 23d 104p 65s 24d 105p 66s 24f 145d 106p 2 The lead electron configuration diagram Example 1s 2 here 2 in superscript form represent number of electrons. Electron filled in orbital is written in the form of superscript.Then electron get paired according to Hund’s rule with their spin in opposite direction followed by Pauli Exclusion Principle.First 1s orbital filled as it has least energy.Step 3: In this step orbital are filled with electrons according to Aufbau principle in increasing order of energy level of orbital.S orbital can hold maximum two electrons, p orbital can hold maximum six electrons and in d and f orbitals 10 and 14 maximum electrons can be filled.S, p, d and f are the four orbitals which hold electrons.Step 2: Second step is to find out orbitals.It is found that lead has 6 electron shell.
