Question

Quizplus · Accepted Answer

Strontium (Sr) has an electron configuration ending in 5s^2. The first electron removed during cation formation comes from the outermost shell, which is the 5s orbital. The quantum numbers for an electron in the 5s orbital are n=5 (principal quantum number), l=0 (azimuthal quantum number for an s orbital), m_l=0 (magnetic quantum number, which is 0 for s orbitals), and m_s can be either +½ or −½ (spin quantum number). Option E correctly represents these quantum numbers for the first electron removed.
