Element Symbols
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. Here's an alphabetical list of element symbols with corresponding element names.

Atomic Weights of the Elements
This is the list of the atomic weights of the elements (2007 IUPAC-accepted values). Elements are listed in order of increasing atomic number.

Atom Diagrams
This is a collection of diagrams of atoms, showing the numbers of protons, neutrons, and electrons present in the atom or isotope of an element.

Electronic Configuration of the Elements
This table is a compilation of the electron configurations of the elements up through number 104. Tips for writing out stable configurations and for shorthand notation are included.

Valences of the Elements
The valences aren't just those you see in the columns of the periodic table! Check out this chart of element valences to help determine potential chemical reactions.

Liquid Elements
What are the six elements that are liquid at or near room temperature? Your About Guide answers this question and provides a few facts about each element.

Elements Listed by Density
See the order of the chemical elements according to their density (mass per unit volume), from least dense to most dense.

Basic Model of the Atom
Are you confused about atoms, elements, protons, neutrons, electrons, isotopes, and ions? Here's a basic look at the model of the atom. It's a great overview for kids or anyone looking to grasp the essentials of atomic theory.
