Give a possible set of values of the four quantum numbers for the 4s and 3d electrons in titanium.

Principal quantum number (n): 4 (since it's the 4s subshell) Angular momentum quantum number (l): 0 (s orbitals have l=0) Magnetic quantum number (ml): 0 (s orbitals have only one value for ml, 0) Spin quantum number (ms): ±1/2 (since there are 2 electrons in the 4s subshell, one will have ms=+1/2 and the other ms=-1/2) The possible set of quantum numbers for the 4s electrons in Titanium are: 1. n=4, l=0, ml=0, ms=+1/2 2. n=4, l=0, ml=0, ms=-1/2

Principal quantum number (n): 3 (since it's the 3d subshell) Angular momentum quantum number (l): 2 (d orbitals have l=2) Magnetic quantum number (ml): -2, -1, 0, 1, 2 (d orbitals have 5 possible values for ml) Spin quantum number (ms): ±1/2 (since there are 2 electrons in the 3d subshell, one will have ms=+1/2 and the other ms=-1/2) The possible set of quantum numbers for the 3d electrons in Titanium are: 1. n=3, l=2, ml=-2, ms=+1/2 2. n=3, l=2, ml=-2, ms=-1/2 3. n=3, l=2, ml=-1, ms=+1/2 4. n=3, l=2, ml=-1, ms=-1/2 (Note: We only have 2 electrons in the 3d subshell, so we stop listing the quantum numbers at ml=-1. If more electrons were present, we would continue listing quantum numbers with the other possible ml values.)
