Four scientists, Cavendish, Moisson, Priestley, and Rutherford, discovered four elements, fluorine (F2), hydrogen (H2), nitrogen (N2), and oxygen (O2). Each of these elements has a different property: One is one of the least reactive elements, one is the most reactive element, one is the most abundant element in the body, and one is the most abundant element in the universe. Can you determine who discovered what element and what each element’s property is?
a. Fluorine, which was not discovered by Cavendish, isn’t the least reactive element.
b. Nitrogen, which was not discovered by Priestley, isn’t the most abundant element in the universe.
c. The four scientists are: Priestley, Rutherford, the discoverer of fluorine, and the discoverer of the element most abundant in the universe.
d. The element found to be the most abundant in the body wasn’t discovered by Moisson and isn’t nitrogen or hydrogen.
