This white-on-black chart shows what atoms look like. This chart shows all the fundamental atomic electron orbitals as electron probability density distributions (fuzzy clouds), which is as close as you can get to visualizing what an atom really looks like. The orbitals are labeled. This elegan...

In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
Electrons are found in different spaces around an atom, which we call electron shells. Each row of the Periodic Table of Elements, called a period, represents a new outer shell of electrons. The elements in each column, called a group, have the same amount of electrons in their outer shell...
In general, chemists and other scientists can use the table to predict how certain elements will react with one another. The alkali metals, for instance, are in the first column or group of the table and tend to have one valence electron and so carry a charge of +1. This charge means ...
The electron configurations of lanthanide cations are similar to those of alkaline earth metal cations, as the inner f- orbitals are largely or completely unavailable for bond formation; (Choppin & Rizkalla 1994) The lanthanide trivalent cations are essentially spherical and present an environment ve...
Periodic Table Orbitals We have all heard of the term orbit when we were at the beginning of this subject but now the right time has come when you get familiar with the various orbitals that divide each element. PDF Some of them are S-orbital, P-orbital, and D-orbitals. However, it ...
each shaped like a propeller blade. Each of the p-orbitals holds two electrons, for a total of six electrons in the p-orbitals. According to Hund's Rule, each p-orbital per energy level must receive one electron before earning a second electron. The p-block starts with the column contain...
Periodic Table of Elements (Interactive) [PDF] - This Interactive Periodic Table is a tabular arrangement of the chemical elements, organized based on chemical element names, symbols, atomic masses, electron configuration and other chemical properties.
The alkali metal family includes the six elements in thefirst columnof the periodic table, fromlithium(Li) down to francium (Fr). These metals all contain one valence electron, meaning they form cations and react readily with water. These elements form the ionic bonds known as salts. ...
