If you expanded an atom to the size of a baseball, what would it look like? With quantum laws in play, the answer isn't as easy -- or intuitive -- as you'd think.
Explore images from particle accelerators that have captured particles in the act of being created or destroyed.
What is a Bose-Einstein condensate? Physicist Luis Orozco gets into the nitty-gritty of this very, very cold substance.
In Mala Radhakrishnan's world, where oxygen and palladium atoms clamor to get into the most sought-after beaker, and tortured carbon atoms become boron swans, chemistry is rift with mystery, jealousy and, yes, romance.
Hear why orbiting electrons drive NOVA scienceNOW host Neil deGrasse Tyson batty.
Explore what holds atoms together to form the myriad chemical substances found in our world.
Bonding, Part II: Students learn to draw electron dot diagrams for atoms and Lewis structures for molecules. Single, double, and triple bonds are defined. Polyatomic ions are described, and students learn to draw Lewis structures for polyatomic ions.
Atomic Theory: Electrons on the Atom Bohr's model of the atom are described. Students calculate wavelength, frequency, or the velocity of a wave using the wave equation and use emission spectroscopy to illustrate the change in energy levels between orbitals.
