The Third Quantum Number
• The third quantum number identifies the orbital that the electron is in.
• An orbital is an area within a sublevel that can hold up to two electrons.
The 4th Energy Level
• How many sublevels are present and what type are they?
• Four sublevels: s, p, d, f
The Fourth Quantum Number
• Also called the spin quantum number.
• Can be either +1/2 or -1/2.
• Specifies the direction of spin of the electron on its axis.
The Fourth Quantum Number
• Also called the spin quantum number.
• Can be either +1/2 or -1/2.
• Specifies the direction of spin of the electron on its axis.
