Chlorine is an element that consists of 17 protons, an average of 18.5 neutrons and 17 electrons. It has an atomic number of 17, and an average nuclear charge of 35.5. There are 2 isotopes of chlorine that are 35Cl and 37Cl. 35Cl has an atomic mass of 35 and a natural abundance of 75%. 37Cl has an atomic mass of 37 and a natural abundance of 25%. The average atomic mass or nuclear charge equates to 35.5. Both of the isotopes have the same atomic number. (BBC Bitesize. Atoms and the periodic table. 2014)

The periodic table distinguishes metals from nonmetals, as the metals are present on the left hand side of the periodic table, and the nonmetals on the right hand side (with the exception of Hydrogen). A diagonal line of elements separate them both and are known as metalloids that have properties of both metals and non-metals. Many periodic tables have a stair-step line on the table to show this separation. This diagonal line starts with boron and ends at polonium. Each of these groups of elements possesses similar properties. (Boundless. 2015)

The position of an element in a periodic table can help you to identify properties of the element. The elements are arranged based on atomic numbers and electronic configurations. Groups of the periodic table indicate the number of valence electrons in an element’s atom. Periods of the periodic table…
