question 143

Multiple Choice

Identify the set of four quantum numbers that could represent the last electron added (using the aufbau principle) to form the Cl atom.

• A)n = 3,l = 1,m_l = 1,m_s = + \(\frac{1}{2}\)
• B)n = 3,l = 0,m_l = 1,m_s = - \(\frac{1}{2}\)
• C)n = 3,l = 2,m_l =1 ,m_s = + \(\frac{1}{2}\)
• D)n = 2,l = 1,m_l = 1,m_s = - \(\frac{1}{2}\)
• E)n = 3,l =2 ,m_l = 1,m_s = - \(\frac{1}{2}\)
