QUESTION: Problem 18P
Write a full set of quantum numbers for the following:
(a) The outermost electron in an Rb atom
(b) The electron gained when an S– ion becomes an S2– ion
(c) The electron lost when an Ag atom ionizes
(d) The electron gained when an F– ion forms from an F atom.
ANSWER:
Solution 18P:
Here, we are going to determine the quantum numbers of the following element.
Step 1:
There are four quantum numbers.
The Principal Quantum Number (n):
The principal quantum number determines the overall size and energy of an orbital. It is an integer.
The possible values are n = 1, 2, 3,..
The Angular Momentum Quantum Number (l): The angular momentum quantum
determines the shape of the orbital. The possible values of l are 0, 1, 2,...., (n - 1).
The Magnetic Quantum Number (ml): The magnetic quantum number specifies the orientation of the orbital. The values of ml will be -l to +l.
The Spin Quantum Number (ms): The spin quantum number specifies the orientation of
the spin of the electron. For an electron the ms =+½ or -½
Therefore,
