"WebAn atom is the most basic unit of an element - all elements have distinct properties because of the structure of their atoms. For example, an atom on the surface of a silicon crystal (see Figure 1) will be different from those on the surface of a uranium crystal.

WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds. WebAn atom is the smallest unit of matter that retains all of the chemical properties of an element. For example, a gold coin is simply a very large number of gold atoms molded into the shape of a coin, with small amounts of other, contaminating elements.
