@JFraser my teacher just gave me this The internet allows us to see and experience the periodic table in a way only accessible to scientists 20 years ago. In 1869 Russian chemist, Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He made predictions about five elements in addition to germanium. You are to research what these elements were and how accurate his predictions were. Express your answer, with your own phrasing, in a minimum of 500 words.
