1.4 Models for Bonding
This unit deals with different models used by teachers to help students visualize chemical bonding. The way that these models are used in class is demonstrated.

Modeling atoms

Teachers’ forum

"We're going to experiment with isotopes next semester. It's always been such a huge problem, the parts of the atom, and having them get that straight. Leslie came up with this idea. We went out and bought a whole bunch of poker chips. They're going to make atoms from poker chips."

"We're going to have protons, neutrons and electrons, and we're going to write the pluses, the minuses, and the zeroes on the poker chips, and just move them. We thought we could use the poker chips to model nuclear reactions and isotope reactions."

"One of the things that really helps when you do this is a really neat board-type thing that uses marbles, with different sizes of marbles, to be able to determine the neutrons, electrons and protons."

Annandale High School, Virginia
