ntum numbers are used to uniquely identify an electron in an atom. The Pauli exclusion principle states that no two electrons in an atom may have the e set of four quantum numbers. Part A List a possible set of four quantum numbers (n, l, me, ms) in order, for the highest energy electron in a gallium (Ga) atom in its ground state. Refer to the periodic table as necessary. Enter four numbers separated by commas (e.g., 3,2,-2,1/2). > View Available Hint(s) Submit P Pearson Copyright © 2020 Pearson Education Inc.

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (), the magnetic quantum number (m), and the spin quantum number (m,) have strict rules which govern the possible values. Identify all allowable combinations of quantum numbers for an electron. On = 5, € = 2, me = 2, m, = - On = 4. € = 1, me = 2, m, = - On = 3, € = -2, me = -2, m, = - On = 6, € = 6, me = 0, m, = + %3D On = 2, = 1. me = -1, m, = 1 On = 3, = 2, m, = -2, m, = -

Using complete subshell notation (not Noble gas configuration; for example: 1s2 2s2 2p6, .....), predict the ground state electron configuration of each of the following atoms: Chromium
