If any of these combination(s) has/have the same energy lists: 1. A. Last Modified Date. For example, an Iodine atom has its outmost electrons in the 5p How many electrons can have n = 3, l = 2, ml = 2, ms = − 12? Answer: Only one electron in a given atom can have the set of quantum numbers given in the question. Angular Momentum (Secondary, Azimunthal) Quantum Number (l): l = 0, , n-1.-. l = 0, m_i = -1 n = 3, l = 1, m_i = +3 n = 3, l = 2, m_i = 3 n = 3, l = 3, m_i = +2 n = 3, l = 2, m_i = -2. of energy for the electrons represented by the following sets of quantum numbers is : 1. Out of these, one half or 16 electrons have m s = + 1 2. s menunjukkan arah perputaran elektron +½ (ke atas) maka pada orbital d terisi 2 elektron. The correct quantum numbers for last electron of Copper ( Cu C u) would be B. Answer link. When n = 3, l has possible values of 0, 1, and 2. n = 4, l = 2, m l = − 2, m s = − 1 / 2 II. In option (a), n = 3, l = 0,1,2 and m = −2,−1,0,+1,+2 where s can have a value of +1 2 or −1 2. n = 4, l = 2, ml = -2 , ms = -1/2 2.5. n = 3, l = 3, = The decreasing order of energy for the electron represented by the following sets of quantum number is (1) n = 4, l = 0, m = 0, s = + 1 2 (2) n = 3, l = 2, m = + 1, s = − 1 2 (3) n = 3, l = 2, m = − 1, s = + 1 2 (4) n = 3, l = 1, m = 0, s = + 1 2 (5) n = 5, l = 2, m = + 1, s = − 1 2 Structure of Atom Class 11 MCQs Questions with Answers. n = 3, l = 2, m = 0, s = +1/2 4. The set of quantum numbers n = 3, l = 0, m = 0, s = -1/2 represents an electron of the element _____.
