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."
