A: periods B: groups C: columns (3 The periodic table is arranged in a series of columns, called _____________. A: groups B: periods C: rows (4 The statement that there is a periodic repetition of physical and chemical properties of the elements when arranged by increasing atomic number is known as what? A: The Mendeleevian Rule B: The Lavoisier Principle C: periodic law D: periodic table (5 In spite of Mendeleevs version of the periodic table being accepted, it contained a fundamental flaw. Ordering the elements by atomic mass led to some elements being out of place. In 1913, an English chemist decided to order the elements by their atomic numbers. Who was this man? A: Henry Moseley B: Lothar Meyer C: Antione Lavoisier D: John Newlands (6 This German chemist was a contemporary of Dmitri Mendeleev in that he also discovered the relationship between atomic mass and elemental properties. However, he did not publish his results in time. What was his name? A: Henry Moseley B: Lothar Meyer C: John Newlands D: Antione Lavoisier (7 This English scientist noticed that properties of elements repeat with every eighth element. He attempted to arrange the elements using the octave as a basis in 1864. Who was he? A: Dmitri Mendeleev B: Lothar Meyer C: Antione Lavoisier D: John Newlands (8 The first list of 23 elements was compiled in the late 1790s by which French scientist?
