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.

Did sir humphrey davy discover chlorine?
No he did not. Carl Wilhelm Scheele discovered it, but he wasn't sure if it was a new element or not. After he died Sir Humphry Davy figured out that chlorine was in fact a new element. How old are asker? I'm twelve.
How can chemists state with certainty that no one will discover an element between sulfur and chlorine?
Elements are distinguished based on their number of protons. Chlorine has exactly one proton more than sulfur. Since there cannot be fractions of protons, there can be no element between sulfur and chlorine on the periodic table.http://wiki.answers.com/Why_will_no_one_ever_find_an_element_between_sulfur_and_chlorine#ixzz17vf65uRN
Explain how chemists can state with certainty that no one will discover an element between sulfur and chlorine?
they are exactly 1 proton away and there can't be fractions of protons so yeh
What element's atomic mass is 35.453?
Chlorine has an atomic mass of 35.453.
How can chemists state 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.
