Periodic Table of Elements
|
 The
Los Alamos National Laboratory's Chemistry Division has an excellent
free online Periodic Table of the Elements.
Click on the element and it provides you with other details such as the atomic number,
symbol and weight, the electron configuration, atomic radius, melting point, boiling
point, oxidation states and history. Where applicable it also has information on
it's forms, properties, isotopes, uses and costs. Very slick.
Trouble learning the elements? KazooToys.com has a great item that will help
you learn while you eat called the Read A Mat Placemat: Periodic Table of Elements
If you want a
wall chart, shirt, cup, etc. with the Periodic Table on them, check out
Edmund Scientific.

The NIST Chemistry WebBook provides
access to data compiled and distributed by NIST (National
Institute of Standards and Technology) under the Standard Reference Data
Program. You can search for data on specific compounds in the
Chemistry WebBook based on name, chemical formula, CAS registry number,
molecular weight, chemical structure, or selected ion energetics and spectral properties.

Did You Know?

The world's largest natural crystals are located in the Cave of Crystals, also known
as Cueva de los Cristales, a chamber located about 1000 feet deep in the Naica Mine
in Chihuahua, Mexico.
Some of the translucent gypsum (selenite) crystal beams in this mine are up to 36
feet long and 4 feet in diameter and weigh up to 55 tons!
The Naica Mine is a lead, zinc and silver mine in which large voids have been found
containing these huge crystals. The Cave of Crystals was discovered because the
mining company's operation continually pumps the water out of these caves, otherwise
it would still be filled with water. Because of the very long period of precise
water temperature and unique conditions in these caves, the crystals were able to
grow this large. If the mining company stopped their pumping operation, these crystals
would presumably continue growing.
The cavern was discovered while the miners were drilling through the Naica fault,
which they were worried would flood the mine.

Dressing up as a
mad scientist can be really fun! Why not create
costumes to really get in the spirit of your next science project.
Kids costumes come in all shapes and sizes so take your time and
come up with something totally original. You could really dream up with some very
funny Halloween costumes
that will make you look like the craziest mad scientist around. Have fun and keep
learning!
