WebThe Pauli exclusion principle states that no two electrons in any one atom can have the same set of four quantum numbers. The highest-energy electron in a potassium atom has one set of four quantum numbers, and the highest-energy electron in a cesium atom has a different set of four quantum numbers. WebFirst, determine which of the chains has the first connection to an atom with the highest priority (the highest atomic number). That chain has the higher priority. If the chains are similar, proceed down the chain, until a point of difference. For example: an ethyl substituent takes priority over a methyl substituent.
