The Periodic Table of Elements

Scientists all around the world use the periodic table, it has three groups the metals, metalloids, and non-metals usually color-coded. The elements in the periodic table want to be chemically stable like the noble gases; therefore, elements form ions by losing or gaining electrons. The elements tend to lose or gain electrons in order to be like the elements that lay directly across the table. The elements that lose electrons become positive ions and visa versa for the elements that lose electrons. Each element on the periodic table has a different atomic symbol, atomic number, and atomic weight. The atomic symbol tells one how many neutrons and electrons that element has, the atomic weight tells the atomic mass of the element, and the atomic symbol shows what element it is.
