As we will see below, the periodic table organizes elements in a way that reflects their number and pattern of electrons, which makes it useful for predicting the reactivity of an element: how likely it is to form bonds, and with which other elements. Electron shells and the Bohr model

There are 118 elements on the periodic table. Each element is identified by the number of protons in its atoms. This number is the atomic number. The periodic table lists the elements in order of increasing atomic number. Each element has a symbol, which is one or two letters. The first letter is always capitalized.
