Unformatted text preview: CHEM 1201 SI Worksheet Quantum Numbers (Use the Electron Configuration Periodic Table!!) n = the principal quantum number = 1, 2, 3, 4, 5 o electrons with the same n belong to one SHELL l = the azimuthal quantum number = 0, 1, 2, 3, 4, 5 , n-1 o l 's value depends on the value of n i. if n = 1, l = 0 ii. if n = 2, l = 0, 1 iii. if n = 4, l = 0, 1, 2, 3 - if l = 0 s subshell - if l = 1 p subshell - if l = 2 d subshell - if l = 3 f subshell o electrons with the same n and l belong to one SUBSHELL o tip: difference between shell and subshell shell is described with only a number ( n , ie: 2); subshell is described with a number and a letter ( nl , ie: 2p) m l = the magnetic quantum number = 0, 1, 2, 3, 4 l o its value depends on the value of l i. if l = 0, m l = 0 1 orbital in s subshell ii. if l = 1, m l = -1, 0, 1 3 orbitals in p subshell iii. if l = 2, m l = -2, -1, 0, 1, 2 5 orbitals in d subshell iv. if l = 3, m l = -3, -2, -1, 0, 1, 2, 3...
