k/u - true or false question 11 (1 point) if $l = 2$, then we are referring to a \d\ orbital. true false question 12 (1 point) the following is a possible set of quantum numbers for an element in the $3^{rd}$ period. $n = 3, l = 1, m_l=-2, m_s = +\frac{1}{2}$ true false
Answer
Explanation:
Step1: Recall orbital - angular - momentum quantum number rules
The orbital - angular - momentum quantum number (l) determines the shape of the orbital. When (l = 0), it's an (s) - orbital; when (l=1), it's a (p) - orbital; when (l = 2), it's a (d) - orbital; when (l=3), it's an (f) - orbital. So for (l = 2), we have a (d) - orbital.
Step2: Recall magnetic - quantum - number rules
The magnetic quantum number (m_l) has values ranging from (-l) to (l). Given (n = 3) (the principal quantum number), (l = 1) (a (p) - orbital). For (l = 1), (m_l) can take values (-1,0,1). Since (m_l=-2) when (l = 1) is not allowed.
