Quantum Numbers
Fichas del conjunto (24)
- 1Quantum Numbersa set of four numbers used to describe the position/ energy of an electron in an atom
- 2Principle Quantum Number (n)denotes the mainshell location of an electron
- 3The number of mainshells in an atom is the same as the number ofthe period in which the element is located on the periodic table
- 4The maximum number of mainshells for the known elements7- the same as the number of periods on the periodic table
- 5The formula used to calculate the possible number of electrons in a given mainshell2n^2
- 6The maximum number of valence electrons8 (octet)
- 7When using letter designation for mainshells start withK and continue through the alphabet
- 8Angular Momentum Quantum Number (l)indicates the sublevel in which the electron is located
- 9Sublevel numbers have integral values from0 to n-1
- 10The number of sublevels possible in a mainshell is equal tothe mainshell number
- 11The greatest number of sublevels in any mainshell is4 (s, p, d, and f)
the letters come from mathematical terms - 12Sublevels correspond toblocks on the periodic table
- 13Sublevel numbers with sublevel letter designations0 s
1 p
2 d
3 f - 14Sublevel letter designation with their maximum number of electronss 2
p 6
d 10
f 14 - 15The number of electrons in a sublevel corresponds tothe number of vertical columns in the respective block on the periodic table
- 16Magnetic Quantum Number (ml)indicates the orbital in which the electron is located
- 17Orbitalregion of space defined by a wave function that can hold two electrons
- 18The magnetic quantum number integral values(-l...0...l)
- 19The number of orbitals in a sublevel ishalf the number of electrons in the sublevel because each orbital can hold 2 electrons
- 20Shape of the p orbitalDumbbell
- 21Shape of the s orbitalSphere
- 22Spin Quantum Number (s)indicates the direction of spin of the electron
- 23Electrons spin in an orbital becausethey have a like charge and are in a small space, so they would spin due to repulsion
- 24The possible values for the spin+1/2 and -1/2
