Chapter 40: Q7Q (page 1246)

An electron in a mercury atom is in the 3dsub-shell. Which of the following mlvalues are possible for it: -3, -1, 0, 1, and 2?

Short Answer

Expert verified

The possible values for 3d the sub-shell of the electron of mercury atom are -1,0,1,2.

Step by step solution

01

The given data

An electron in a mercury atom is in the 3d sub-shell.

02

Understanding the concept of the subshell of an orbital

Using the concept of possible values for the magnetic quantum number that depends on the orbital angular quantum number, we can get the required possible values of the magnetic number.

For every l value of a subshell, we have -l to +I possible m values for the same electron.

03

Calculation of the possible values of ml

We have an electron of mercury atom in 3d subshell; thus, the value of the orbital quantum number is given by:

I=2n=3,forthedsubshell

Thus, the possible values ofml are: -2,-1,0,1,2.

Hence, the possible values considering the question are -1,0,1,2.
