3. The quantum numbers of six electrons are given below. a) n=4,l=2,ml=-2,ms=-1/2 b) n=3,l=2,ml=1,ms=+1/2 c) n=4,l=1,ml=0,ms=+1/2 d) n=3,l=2,ml=-2,ms=-1/2 e) n=3,l=1,ml=-1,ms=+1/2 f) n=4,l=1,ml=0,ms=+1/2 Answer below questions (a) which of the electrons are in same energy level (b) which of the electron is having lowest energy (c) which of the electron is having highest energy

(a) The energy level of an electron is determined by the principal quantum number (n). Therefore, electrons with the same value of n are in the same energy level. In this case, electrons a), c), f) are in the same energy level (n=4).<br /><br />(b) The energy of an electron is determined by the sum of its quantum numbers. The lower the value of n, the lower the energy of the electron. Therefore, electron b) has the lowest energy because it has the lowest value of n (n=3).<br /><br />(c) Similarly, the higher the value of n, the higher the energy of the electron. Therefore, electron a) has the highest energy because it has the highest value of n (n=4).
