not a definite path. You cannot determine it's position and it's momentum.
Space Orbital ✅The highly probable location of an electron
Quantum Numbers ✅The set of the numbers that describe the space orbitals of electrons
Principal Quantum Numbers ✅-tells the distance of electrons
-is the energy level for the electron
-is the shell
-Is the row on the periodic table
Azimuthal Quantum Number ✅Indicates shape of the sub level
-S- first sub level (1)
-P- second sub level (3)
-D- third sub level (5)
-F- fourth sub level (7)
Spin Quantum Number ✅Shows the spin Property of electrons
When moving clockwise it's +1/2
