Question

you can use this periodic table during the quiz. however, as stated in the course outline, and in the orientation session, this quiz is not open book. you cannot access course material while you write the quiz. nor can you google your answers, work as a group, use a cheat sheet, etc. question 26 (2 points) i am thinking of a specific electron that is located in the valence shell of a chlorine atom. if its ( m_{1} ) value is +1, what are the four quantum numbers for this electron?

Explanation:

Step1: Determine principal quantum number ($n$)

Valence shell of Cl is 3rd shell, so $n=3$.

Step2: Determine azimuthal quantum number ($l$)

Valence electrons of Cl are in 3s and 3p subshells. For $m_l=+1$, $l$ must be 1 (since $m_l$ ranges from $-l$ to $+l$; $l=0$ (s) has only $m_l=0$). So $l=1$.

Step3: Confirm magnetic quantum number ($m_l$)

Given $m_l=+1$.

Step4: Determine spin quantum number ($m_s$)

Electrons have spin $+\frac{1}{2}$ or $-\frac{1}{2}$; both are possible.

Answer:

$(n, l, m_l, m_s) = (3, 1, +1, +\frac{1}{2})$ or $(3, 1, +1, -\frac{1}{2})$
