![]() Electrons can be arranged correctly through orbits from elements 1 to 18. Therefore, the order of the number of electrons in each shell of phosphorus atom is 2, 8, 5. Therefore, the phosphorus atom will have two electrons in the first shell, eight in the 2nd orbit, and five electrons in the 3rd shell. That is, the number of electrons in phosphorus is fifteen. Position of phosphorus(P) in the periodic table The atomic number is the number of electrons in that element. Therefore, the maximum electron holding capacity in the first shell is two, the second shell is eight and the 3rd shell can have a maximum of eighteen electrons. The maximum electron holding capacity in N orbit is 2n 2 = 2 × 4 2 = 32. The maximum electron holding capacity in M orbit is 2n 2 = 2 × 3 2 = 18. ![]() The maximum electron holding capacity in L orbit is 2n 2 = 2 × 2 2 = 8. The maximum electron holding capacity in K orbit is 2n 2 = 2 × 1 2 = 2. The electron holding capacity of each orbit is 2n 2. K is the name of the first orbit, L is the second, M is the third, and N is the name of the fourth orbit. These circular paths are called orbit(shell). The electrons of the atom revolve around the nucleus in a certain circular path. The complete idea of the orbit is given there. Scientist Niels Bohr was the first to give an idea of the atom’s orbit. Electron configuration of phosphorus through orbit For example Aufbau principle, Hund’s principle, and Pauli’s exclusion principle. ![]() ![]() Phosphorus(P) atom electron configuration(Bohr model)Įlectron configuration through orbitals follows different principles. ![]()
