Defines the spatial orientation of the orbital in a magnetic field. −lnegative l +lpositive l (including ). Total values = 4. Spin Quantum Number ( Defines the direction of electron spin on its own axis. +12positive one-half (Clockwise ↑up arrow −12negative one-half (Counter-clockwise ↓down arrow Rules for Filling Electrons in Orbitals
A well-defined circular path around the nucleus where an electron revolves (Bohr's concept). Defines the spatial orientation of the orbital in
Maxwell’s electromagnetic theory states that an accelerating charged particle (like a revolving electron) must continuously lose energy. If true, the electron would spiral into the nucleus, making the atom unstable. 3. Developments Leading to Bohr’s Model Spin Quantum Number ( Defines the direction of
: The impossibility of simultaneously determining an electron's exact position and momentum. Quantum Mechanical Model : Deep dive into Quantum Numbers If true, the electron would spiral into the
