"The Phantom has provided you with a simulated spectroscopy of an Atom! Amuse the Phantom by observing the spectroscope and you'll learn more about the Atom." Observe and review the structure of the atom.

Read and fill in the blanks of this passage explaining quarks inside the atom. Each blank has a dropdown menu with choices. When you finish, click CHECK MY ANSWERS. If you pick a wrong answer, the right answer will be displayed along...

[Free Registration/Login may be required to access all resource tools.] The nucleus of an atom and what holds it together.

Observe the probable location of electrons around an atom. Trace the electrons over time to draw conclusions about where electrons are likely to be found around an atom's nucleus. How does the trace pattern relate to the electron cloud...

Take a look at the parts of an atom and learn about its properties.

This lesson will illustrate that an atom is mostly empty space and has a positively charged, massive core (containing both protons and neutrons called the nucleus) surrounded by negatively charged electrons. It is 2 of 3 in the series...

This online slide show presents the basic ideas behind the structure of the atomic nucleus.

Describes the structure of an atom and the characteristics of the electrons, neutrons, and protons inside it. Includes some interesting facts about atoms.

Students will find an explanation of the neutron particle located inside the atom's nucleus. Website also defines isotopes and the process of radioactive decay.

The website provides an explanation of the electrons' position in their orbitals as they spin around the nucleus. Quantum theory is also explored by explaining that the exact location of a specific electron is a not exact but a guess.

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...

Learn about Thomson's cathode ray experiment and the plum pudding model and Rutherford's gold foil experiment.

Visit this site for an interactive tour of the atom and all aspects of particle physics. View the animations available with almost every description on this site. A great place for the fundamentals of particles and forces including a...

Explains basic information about the nucleus of an atom.

[Free Registration/Login may be required to access all resource tools.] Rutherford's discovery of the nucleus and his planetary model of the atom.

Dutch version of the well-known "Particle Adventure" physics website that teaches students about atoms, mass, particle physics, and quantum physics. The site discusses theories related to physics and provides other links related to the...

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...

Students interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom.

Investigate why a charged object is attracted or repelled by another charged object. Explore the concept that the attraction between positive protons and negative electrons holds an atom together.

Students discover the concept that two atoms can attract and form a covalent bond.

Students discover that ionic bonding occurs when electrons are transferred from one atom to the other and not shared as in covalent bonding.

Provides a definition and explanation of fission, the splitting of a heavy nucleus into two roughly equal parts, and fusion, the process where two nuclei combine together to form a larger nucleus.

This personal page describes the history and technical facts of the atom, including the nucleus, nucleons, the Bohrs atom, the electron, and more.
