In this activity, students will explore several different models of the hydrogen atom and compare and contrast them using an online java applet.

A well designed clear tutorial explaining the energies involved in the Bohr model of the atom. Illustrations add to the clearly presented equations.

From the Brockport High School Physics Labs web pages. Includes an excellent graphic depicting the energy levels of a hydrogen atoms and portraying the electron level transitions for the Lyman, Balmer, and Paschen series. Includes both...

This site from Georgia State University gives information on the transitions of electrons between energy levels. The energy levels for electrons in the hydrogen atom are discussed. The Rydberg equation is stated and electron transitions...

A lab activity from an AP Physics course. Students measure the energy changes associated with electron level transitions to the second energy level for hydrogen gas. Includes directions and suggestions. Ideal for a student project or lab...

How Bohr's model of hydrogen explains atomic emission spectra.

This brief entry describes the hydrogen ion, strictly, as the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton.

1HNMR theory begins in the nucleus of hydrogen. Complete this tutorial on the 1HNMR spectrum graph to learn about the number of equivalent hydrogens, b) the chemical environment of each hydrogen type and c) the number of neighbouring...

An outstanding site that can best be described as student friendly. It describes the main differences between the classical and quantum models of the atom. Clear and well illustrated.

This is a simple picture of a hydrogen atom using the Bohr model. A negatively charged electron can be seen on the outside of the positively charged proton.

This module simulates the excitation of hydrogen atoms through irradiation with electromagnetic radiation of different wavelengths.

Explore energy during a reaction between hydrogen and oxygen atoms.

From the Brockport High School Physics Labs web pages. Includes an excellent graphic depicting the energy levels of a hydrogen atoms and portraying the electron level transitions for the Lyman, Balmer, and Paschen series. Includes both...

This lesson will introduce the molecular structure of water, including the Hydrogen atoms, Oxygen atoms, and types of bonds. It is 2 of 4 in the series titled "Molecular Structure of Water."

This lesson will introduce the molecular structure of water, including the Hydrogen atoms, Oxygen atoms, and types of bonds. It is 3 of 4 in the series titled "Molecular Structure of Water."

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating...

This tutorial contains links to explanations of the four different quantum numbers (principal, orbital, magnetic, and spin). Equations for each are provided.

At this website from The Nobel e-Museum, read about Harold Clayton Urey (1893-1981 CE), the chemist awarded with a Nobel Prize "for his discovery of heavy hydrogen." Download Urey's Nobel Lecture, "Some thermodynamic properties of...

[Free Registration/Login may be required to access all resource tools.] The following online tutorial describes how the electronegativity difference between two atoms in a covalent bond results in the formation of a nonpolar covalent,...

Through informational text, interactive activities, animations, and video clips, students examine the chemistry of living things, and they learn how interactions from atoms are fundamental to life as we know it.

This resource presents a biography of Bohr, including many personal tidbits, as well as a substantial treatment of his scientific work. Several interesting quotes by and about Bohr are included. It also links to several other sources.

[Free Registration/Login may be required to access all resource tools.] Explains the basic principles of the Bohr hydrogen atom.

In MRI, magnetic fields and radio wave pulses combine to get a unique, and medically beneficial, response from your body's hydrogen atoms. Take a peek in this tutorial.
