History of Periodic Table of Elements

Front

Who arranged the known elements into horizontal rows of increasing atomic mass leaving gaps for as yet undiscovered elements?

Back

Mendeleev

Front

Who constructed a similar table to Mendeleev based on increasing atomic mass but did not leave gaps?

Back

Meyer

Front

Who suggested that the physical and chemical properties were related to the atomic number, rather than atomic mass? Options: Meyer, Mendeleev, Moseley, Newlands

Back

Moseley

How did Dmitri Mendeleev predict elements?

Back

Calculated the atomic mass and properties

John Newlands

Front

What did the "Law of Octaves" state?

Back

The properties of the elements repeated every eighth element when arranged by their atomic mass
