Chlorine compounds have been important to humans for thousands of years. Ordinary table salt, for example, is sodium chloride (NaCl). Still, chlorine was not recognized as an element until 1774, when Scheele was studying the mineral pyrolusite. Pyrolusite consists primarily of manganese dioxide (MnO 2 ). Scheele mixed pyrolusite with hydrochloric acid (HCl), then called spiritus salis. He found that a greenish-yellow gas with a suffocating odor "most oppressive to the lungs" was released. The gas was chlorine.

How can chemists state with certainty that no one will discover an element that would appear on the periodic table between sulfur and chlorine?
An element is characterized by a particular atomic number, which must be an integer since it corresponds to the number of protons in each atom of the element. There is no integer between the atomic numbers of sulfur and chlorine.

What is the trivia of chemistry?
A number of chemists died using the old scientific method of discovering the elements. They had to use as many of the 5 senses as possible and never lived to discover element 17 on the periodic table. The chlorine gas just killed them before they could discover it.Read more: What_are_10_pieces_of_trivia_about_chemistry
