Quantum Numbers

Question 1

What are the 4 Quantum variables

Answer 1

The Principle Quantum Number
The secondary Quantum number
Magnetic Quantum number
Spin Quantum number

Question 2

Principle quantum number

Answer 2

• describes size and energy of orbital (Is the orbital)
• The orbitals increase by full integers that correspond to specific energy levels
• Spaces between orbitals are not equal
• n=1 is ground state

Question 3

Secondary Quantum number

Answer 3

• s-orbital or l=0 is spherical
• p-orbital or l=1 is double lobed
• d-orbital or l=2 and f-orbitals or l=3 are made up of more complex lobes
• These sub-levels always exist from ) to N-1

Question 4

Magnetic quantum Number

Answer 4

• breaks the sublevels into individual orbitals
• defines the spatial orientation along a standard set of coordinates
• is l=2 than ml= -2,-1,0,1,2

Question 5

Spin Quantum Number

Answer 5

• Electrons act like mini-magnets, where spinning creates a magnetic field
• It is describes as ms and there are two possible values

Question 6

Pauli Exclusion Principle

Answer 6

states that within the same atom, no two electrons can have all four of its quantum
