Category:Periodic table



Elements are arranged into the periodic table based on properties they share in common. Each cell of the table contains a different element. The cells of most periodic tables contain the name and symbol of each element, the atomic number (the number of protons), and the atomic mass (number of protons + neutrons). Some periodic tables will contain other information, such as the electron shell configuration of each element, or their state at room temperature (liquid, gas, or solid).
