Circle each of the following that represent an acceptable set of quantum numbers for an electron in an atom:
a) n = 2, l = 1, m_l = 0, m_s = -1/2
b) n = 3, l = 2, m_l = 3, m_s = +1/2
c) n = 4, l = 2, m_l = -2, m_s = -1/2
d) n = 1, l = 0, m_l = 0, m_s = -1/2
Describe the error in each incorrect set:
a) Incorrect because the value of m_l is not within the allowed range of -l to +l.
b) Incorrect because the value of m_l is not within the allowed range of -l to +l.
c) Correct set.
d) Incorrect because the principal quantum number (n) cannot be zero.
