Chapter 6: Problem 58

Give the values for \(n, l\), and \(m_{l}\) for (a) each orbital in the \(2 p\) subshell, (b) each orbital in the \(5 d\) subshell.

Short Answer

Expert verified
For the 2p subshell: \(n = 2\), \(l = 1\), and \(m_l\) values are -1, 0, and +1. There are three orbitals with quantum numbers (2, 1, -1), (2, 1, 0), and (2, 1, +1). For the 5d subshell: \(n = 5\), \(l = 2\), and \(m_l\) values are -2, -1, 0, +1, and +2. There are five orbitals with quantum numbers (5, 2, -2), (5, 2, -1), (5, 2, 0), (5, 2, +1), and (5, 2, +2).

Step by step solution

01

Identify the values of n and l

In the 2p subshell, the principal quantum number n is 2 (it comes directly from the number in subshell notation), and the azimuthal quantum number l is associated with the letter p. The values of l are as follows: \(s = 0, p = 1, d = 2, f = 3, ... \) In this case, l = 1 because we are dealing with the p subshell.
02

Identify the values of ml for the p subshell

For the p subshell (l = 1), the magnetic quantum number ml can take values from -l to +l, with a step of 1, including 0. So for a p subshell (l = 1), ml can be -1, 0, or +1.
03

Write the values of n, l, and ml for each orbital in the 2p subshell

The 2p subshell has three orbitals, which can be represented by the quantum numbers: (a) n = 2, l = 1, ml = -1 (b) n = 2, l = 1, ml = 0 (c) n = 2, l = 1, ml = +1 For the 5d subshell:
04

Identify the values of n and l

In the 5d subshell, the principal quantum number n is 5, and the azimuthal quantum number l corresponds to the letter d. As stated earlier, for the d subshell, l = 2.
05

Identify the values of ml for the d subshell

For the d subshell (l = 2), the magnetic quantum number ml can take values from -l to +l, with a step of 1. So for a d subshell (l = 2), ml can be -2, -1, 0, +1, or +2.
06

Write the values of n, l, and ml for each orbital in the 5d subshell

The 5d subshell has five orbitals, which can be represented by the quantum numbers: (a) n = 5, l = 2, ml = -2 (b) n = 5, l = 2, ml = -1 (c) n = 5, l = 2, ml = 0 (d) n = 5, l = 2, ml = +1 (e) n = 5, l = 2, ml = +2

Most popular questions from this chapter

(a) What is the frequency of radiation whose wavelength is \(0.86 \mathrm{~nm}\) ? (b) What is the wavelength of radiation that has a frequency of \(6.4 \times 10^{11} \mathrm{~s}^{-1}\) ? (c) Would the radiations in part (a) or part (b) be detected by an X-ray detector? (d) What distance does electromagnetic radiation travel in \(0.38 \mathrm{ps}\) ?

For orbitals that are symmetric but not spherical, the contour representations (as in Figures \(6.23\) and 6.24) suggest where nodal planes exist (that is, where the electron density is zero). For example, the \(p_{x}\) orbital has a node wherever \(x=0\). This equation is satisfied by all points on the \(y z\) plane, so this plane is called a nodal plane of the \(p_{x}\) orbital. (a) Determine the nodal plane of the \(p_{z}\) orbital. (b) What are the two nodal planes of the \(d_{x y}\) orbital? (c) What are the two nodal planes of the \(d_{x^{2}-y^{2}}\) orbital?

(a) Calculate the energy of a photon of electromagnetic radiation whose frequency is \(2.94 \times 10^{14} \mathrm{~s}^{-1}\). (b) Calculate the energy of a photon of radiation whose wavelength is \(413 \mathrm{~nm}\). (c) What wavelength of radiation has photons of energy \(6.06 \times 10^{-19} \mathrm{~J}\) ?

(a) State the Pauli exclusion principle in your own words. (b) The Pauli exclusion principle is, in an important sense, the key to understanding the periodic table. (c) Explain.

Calculate the uncertainty in the position of (a) an electron moving at a speed of \((3.00 \pm 0.01) \times 10^{5} \mathrm{~m} / \mathrm{s},(\mathbf{b})\) a neutron moving at this same speed. (The masses of an electron and a neutron are given in the table of fundamental constants in the inside cover of the text.) (c) Based on your answers to parts (a) and (b), which can we know with greater precision, the position of the electron or of the neutron?
