Images in this presentation are excerpted from our Pinterest board of the same title and contains thumbnail images from vintage #chemistry movies found at internetarchive.org. We like the sincerity, the mosaic patterns and the tonality gradients. Also, a couple chemistry jokes and links to two videos featuring a Sentry Air chemist.

National Chemistry Week 2013
National Chemical Week is sponsored by the
American Chemical Society. Images in this
presentation are excerpted from our Pinterest
board of the same title and contains thumbnail
images from vintage #chemistry movies found at
internetarchive.org. We like the sincerity, the
mosaic patterns and the tonality gradients. Also,
a couple chemistry jokes.

2. Measuring ionization energy
Animation shows what occurs on the atomic level during
the ionization process. Ionization energy is defined as the
minimum energy needed to remove an electron from a
gaseous atom, with energy per mole being a more practical
unit to use. Relation of ionization energy to chemical
reactivity is explained. . .more:

4. Vanadium
The different oxidation states of vanadium, a typical transition element, and the corresponding colors are observed,then
identified by means of a quantitative titration of vanadium (II)
solution with cerium (IV) solution. The oxidation states and
the observed colors are…more:

7. At Sentry Air, chemists play a key role in
matching our customers' chemical applications
to our filtration media.
Our chemists also demonstrate their expertise online. Here are
links to two recent videos by our friendly chemist, Ben.
