705 views

The Klechkowski rule, also known as the Aufbau principle, dictates the order in which atomic orbitals are filled with electrons. According to this rule, electrons fill orbitals starting with the lowest energy first. The sequence follows the order of increasing energy levels: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, and so on. This principle helps in predicting the electron configurations of atoms, which is crucial for understanding chemical bonding and properties.
