Periodic table(3)

The presentation of the information makes the periodic table easy to use and understand. The Periodic Table complies with section 5.6 of the New Jersey Education Standards for Chemistry which deals with physical science and chemistry. The in-depth data provided about the elements allows the periodic table to be utilized by beginners and professional in chemistry. "Periodic Table (3)" is a good interactive resource that can be applied to chemistry at the beginner level all the way up through the undergraduate level. Professors can use the applet to increase classroom participation and get students involved. The provided puzzles are also beneficial due to the fact that instructors can use them for quizzes and tests.

The atomic number, mass, atomic radius, melting and boiling point were found to be correct when compared to the data from http://periodic.lanl.gov/default.htm, a periodic table from the Los Alamos National Laboratory's Chemistry Division. Furthermore, the electronegativity, ionization energy, electron affinity, and oxides were found to be accurate when compared to http://www.chemicool.com/, an online periodic table. Also, the formula to mass control is accurate, but the elements can only be input by clicking the periodic table. In addition, the different property arrangements are effective when visualizing the periodic table and the puzzles provided are good practice to learn the periodic table. The puzzles also show users there mistakes when solving the puzzle.

"Periodic Table (3)" is an interactive Java based applet that is clickable and features many tools to explore the periodic table. The periodic table was created by Brian P. Reid and published by Dartmouth College. The operating systems used while running the applet was Microsoft Windows XP Professional and Mac OS 9. Using the Internet Explorer and Mozilla Firefox browsers, the applet runs without any problems. The same can be said for the Safari browser when using a Mac. On the site, located at, http://www.dartmouth.edu/~chemlab/info/resources/p_table/Periodic.html, the periodic table is simple to use. Information that can be found on the webpage is data regarding the atomic spectra, atomic number, and further in-depth statistics. Additionally, puzzles that require the user to arrange elements in the periodic table can be used.
