Explanation Electrons are distributed in the orbitals of the sub-shell. The specific region of space in which the movements of electrons are confined is said to be shells which are divided into sub-shells and are s-, p-, d-, and f-. Among these sub-shells, the electrons are grouped as orbitals. The numbers of electrons that these sub-shells can hold are: s-block - 2 p-block - 6 d-block - 10 f-block - 14 The increasing order of energy of shells, sub-shell is: As the number of electron(s) for a neutral atom is equal to the atomic number of an atom. Thus, For atomic number of the element 123, means the atom contains 123 electrons. These 123 electrons are arranged in orbitals by using the Aufbau principle. So, the electronic configuration can be given as follows: 123 = 1 s 2 2 s 2 2 p 6 <
