Long Answer TypeWhat are quantum numbers? Explain briefly the various quantum numbers which completely specify an electron in an atom.
Short Answer TypeAn electron is placed in 4f orbital. What possible values for the quantum numbers, n, l, m and s can it have?
For 4f orbital, n = 4, l = 3
When l=3, m = -3, -2. -1, 0 + 1, +2, +3. (seven values)
For each value of m, there are two possible values for s i.e. + 1/2 and - 1/2 .
(i) An atomic orbital has n = 3. what are the possible values of l and ml ?
(ii) List the quantum number (ml and l) of electrons for 3d orbital.
(iii) Which of the following orbitals are possible: 1p, 2s, 2p, and 3f?
How many electrons in an atom may have the following quantum numbers?
(a) n = 4, ms = - 1/2 (b) n = 3, l = 0
Using s, p, d notations describe orbital with the following quantum numbers:
(a) n = 1, l = 0; (b) n = 3; l = 1 (c) n = 4; l = 2; (d) n =4, l = 3.
