Overview
Quantum numbers are essential for describing the unique state of electrons in atoms. They provide a systematic way to understand the arrangement and behavior of electrons, which is crucial for predicting chemical properties and reactions. Each quantum number has a specific role, from defining energy...
Key Terms
Example: The principal quantum number (n) indicates the energy level of an electron.
Example: For hydrogen, n = 1 is the ground state.
Example: l = 0 corresponds to an s orbital, while l = 1 corresponds to a p orbital.
Example: For p orbitals, m_l can be -1, 0, or +1.
Example: m_s can be +1/2 or -1/2.
Example: The electron configuration of carbon is 1s² 2s² 2p².
