115. Electronegativity Three dimensional periodic table of electronegativity. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Electronegativity.html

Index to this page Ionic Bond Covalent Bond Polar Covalent Bond Electronegativity The affinity for electrons. The atoms of the various elements differ in their affinity for electrons. This image distorts the conventional periodic table of the elements so that the greater the electronegativity of an atom, the higher its position in the table. Although fluorine (F) is the most electronegative element, it is the electronegativity of runner-up oxygen (O) that is exploited by life. The shuttling of electrons between carbon (C) and oxygen (O) atoms powers life. Moving electrons against the gradient (O to C) - as occurs in photosynthesis - requires energy (and stores it). Moving electrons down the gradient (C to O) - as occurs in cellular respiration - releases energy. The relative electronegativity of two interacting atoms also plays a major part in determining what kind of chemical bond forms between them. Example 1 : Sodium (Na) and Chlorine (Cl) = Ionic Bond There is a large difference in electronegativity, so the chlorine atom takes an electron from the sodium atom converting the atoms into ions (Na ) and (Cl These are held together by their opposite electrical charge forming ionic bonds Each sodium ion is held by 6 chloride ions while each chloride ion is, in turn, held by 6 sodium ions.

119. Chem-It Free Windows software for novice Chemistry students. Includes periodic table and conversion charts. http://www.siteup.com/chemit/

CHEM-IT PASSES 35,000 REGISTERED USERS! Summary: Chem-It is a program for the novice Chemistry student. I always found that I could never get everything together when I was doing my Chemistry problem sets. I'd always be juggling between the periodic table, conversion charts, and my laptop. Chem-It was designed in response to this problem. Program: Chem-It offers everything the Chemistry student needs to work efficiently. The program performs common conversions automatically. There are reference areas which contain commonly used constants. The interactive periodic table houses all information a student might need about each element. The mass calculator allows you to calculate the mass of very complex substances using simple menus. During experiments, there is a built-in timer which makes it easy to time reactions. Additionally, there is a built in text editor which allows you to type your experiment notes without leaving the program. Click here to see some screenshots of Chem-It.

Periodic Table Memory Pegs Icons drawn by David R. Pratt 16 September 1997 updated 4 March 2000 to show data with mouse Each picture in this periodic table is designed to remind you of the element's name, atomic number, and abbreviation. Point to the element to see its name and number. Click on the element for more explanation and then "Back" to return to the table. There is also an explanation of how to use the pictures as memory pegs. You can also see the name and number of the element by pointing to it and reading the address in the status window at the bottom. At least memorize the first twenty! Each of those first 20 also has a unique color which can also be used for memorizing a list of tweny objects by associating a color with each. Atomic Numbers Back to John Pratt's Home Page
