Chapter 7: Problem 59

List the hydrogen orbitals in increasing order of energy.

Short Answer

Expert verified
The hydrogen orbitals in increasing order of energy are 1s, 2s = 2p, 3s = 3p = 3d, and so on.

Step by step solution

01

Understanding Atomic Orbitals

An atomic orbital is a region in an atom where there is a high probability of finding an electron. Each orbital is associated with a specific energy level (principal quantum number, n) and shape (orbital type, l). Here, we have to list hydrogen atomic orbitals (which host electrons).
02

Identifying Principal Quantum Numbers

The principal quantum number (n) tells us the energy level of the electron and the size of the orbital. The minimum value of 'n' is 1. Increasing values of n mean higher energy and the orbital is located further from the nucleus.
03

Listing the Hydrogen Orbitals

Hydrogen atomic orbitals are typically labeled as 1s, 2s, 2p, 3s, 3p, 3d and so on, where the number refers to the principal quantum number n, and the letter refers to the type of orbital (s, p, or d). For hydrogen (or any one-electron ion), the energy of the orbital increases with n, regardless of the type of orbital. Therefore, the order of energy increasing order of hydrogen atomic orbitals is 1s, 2s = 2p, 3s = 3p = 3d, and so on.

What is the de Broglie wavelength, in centimeters, of a 12.4-g hummingbird flying at \(1.20 \times 10^{2} \mathrm{mph} ?\) \((1 \mathrm{mile}=1.61 \mathrm{~km})\)

The \(\mathrm{He}^{+}\) ion contains only one electron and is therefore a hydrogenlike ion. Calculate the wavelengths, in increasing order, of the first four transitions in the Balmer series of the \(\mathrm{He}^{+}\) ion. Compare these wavelengths with the same transitions in a \(\mathrm{H}\) atom. Comment on the differences. (The Rydberg constant for \(\mathrm{He}^{+}\) is \(\left.8.72 \times 10^{-18} \mathrm{~J} .\right)\)

What properties of electrons are used in the operation of an electron microscope?

A laser produces a beam of light with a wavelength of \(532 \mathrm{nm}\). If the power output is \(25.0 \mathrm{~mW}\), how many photons does the laser emit per second? \((1 \mathrm{~W}=1 \mathrm{~J} / \mathrm{s})\)
