Sequencing Event
Directions: Arrange in chronological order the development of the
periodic table. Write letters from A to Eon the space
provided.
1. John Newlands (Great Britain) arranged the elements in order of
their increasing atomic weights into sets of eight elements called
Law of Octaves.
2. Antoine Lavoisier (France) arranged the elements into groups of
simple substances that do not decompose by any means.
3. Dmetri Mendeleev (Russia) arranged the elements in order of
increasing atomic weights in a graphical method; but in addition, he
left gaps for still undiscovered elements.
4. Johann W. Dobereiner (Sweden) arranged the elements in triads.
5. Lothar Meyer (Germany) arranged elements in order of
increasing atomic weights in graphical method made by
plotting atomic volume against the relative atomic mass
explaining the anomalies in Newland's Table.​
