Describe how the model of the atom advanced as scientific knowledge increased. This lesson is 3 of 3 in the series titled "Models of the Atom."

Explains what Bohr's model of the atom is, the characteristics of the ground and excited states of an atom, and the electron configuration for each in the example of Phosphorus.

As part of the General Chemistry Virtual Textbook, this site examines a list of related topics (in hyperlink format) on the atom and the Periodic Table of elements. Topics from light, particles, and waves to the Bohr model, quantum...

Looks at the scientists who developed the model of the atom by building on previous scientists' discoveries about its structure.

A classroom wiki where students present profiles of scientists who developed models of the atom or who contributed to the understanding of atomic theory. Covers Democritus, Aristotle, John Dalton, J.J. Thomson, Ernest Rutherford, Marie...

Slideshow looking at the history of models of the atom, including those proposed by John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick. Discusses subatomic particles, including the numbers of protons, neutrons,...

Short slideshow looking at the history of models of the atom, including the contributions of Aristotle, Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses Niels Bohr and his work with the atom. This part of the discussion, focusing on the model itself, brings up...

[Free Registration/Login Required] Explore the Bohr model of atoms by studying the absorption and emission of light from simple gases in the context of starlight using this interactive simulation. A PDF worksheet and a video tutorial are...

Describe how the model of the atom advanced as scientific knowledge increased. This lesson is 1 of 3 in the series titled "Models of the Atom."

An explanation of Niels Bohr's (1885 - 1962 CE) Model along with an app that illustrates a hydrogen atom according to the particle or wave model. You can choose a principal quantum number "n." The right part of the graphic represents the...

The Nobel Foundation provides this site about Niels Bohr's contributions to the world of physics, specifically his "investigation of the structure of atoms and of the radiation emanating from them." This biography includes information on...

Presents the history of the atom with a New Age perspective on some aspects. It describes the concept of the atom in Vedic philosophy and that developed by Democritus. Goes on to look at the models proposed by John Dalton, J.J. Thomson,...

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.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the hydrogen atom and its relation to spectrum. Included in the discussion is information on the Bohr model...

All matter is made of atoms! And atoms are made of even smaller more fundamental particles. Atoms are not shiny little rigid spheres as we depict in drawings and simulations; they're more like a squishy storm of tiny particles swirling...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses Niels Bohr and his work with the atom. Topics covered in the discussion include the atom before Bohr, Bohr's...

[Free Registration/Login may be required to access all resource tools.] Rutherford's model of the atom was better than earlier models. But it wasn't the last word. Danish physicist Niels Bohr created a more accurate and useful model....

Scientists' understanding of the structure of the atom and of its component particles grows, the phone and radio become common, and the modern television is born.

[Free Registration/Login Required] Shown here are representations of three different models of the atom. Move the name labels to correctly title each of the models with the scientist who created them.

PBS offers a short summary of the discovery of the quantum nature of the atom by Max Planck. Easy to follow.

[Free Registration/Login may be required to access all resource tools.] Students learn about the important discoveries of subatomic particles, and how they led to our current understanding of the atom.

Tutorial provides a discussion of UV-Vis spectroscopy, infrared (IR) spectroscopy, and the Beer-Lambert law.
