Why do elements in a family (column) on the periodic table have similar properties? List three different metals. Give examples of how each metal is used. An atom contains 74 protons, 74 electrons, and 108 neutrons. Which element is it? A chemistry student claims to have discovered a new element. The student states that the new element has properties similar to fluorine and chlorine, and he argues that it should be placed between fluorine and chlorine in the periodic table. Could the student have discovered a new element? Explain.
