Question

the possible values for angular momentum quantum number, l, when n = 3 are
a.0,1,2,3
b.-1,0,1,2
c.0,1,2
d.-3,-2,-1,0,1,2,3

question 13
the possible values of magnetic quantum number, ml when l = 0 are
a.0
b.0,1
c.0,1,2
d.0,1,2,3

question 14
how many electrons will fit into the orbital with quantum numbers n = 4, l = 2 and ml = 0
a.5
b.10
c.2
d.1

question 15
which of the following sets of quantum numbers is for the highest energy orbital

Explanation:

Step1: Recall angular - momentum quantum number rule

The angular - momentum quantum number \(l\) ranges from \(0\) to \(n - 1\). Given \(n = 3\), \(l=0,1,2\).

Step2: Recall magnetic quantum number rule

The magnetic quantum number \(m_l\) ranges from \(-l\) to \(+l\). When \(l = 0\), \(m_l=0\).

Step3: Recall electron - capacity of an orbital

An orbital can hold a maximum of 2 electrons regardless of the values of \(n\), \(l\), and \(m_l\).

Answer:

Question 12: c. 0, 1, 2
Question 13: a. 0
Question 14: c. 2
