How did Newland's
Law of Octaves
organise the periodic table?

6
Why was Newlands' table of elements called "periodic"?
His colleague suggested the name
similar properties occured at regular intervals
They were published in periodic science journals

23
How is the modern periodic table different from Newlands' and Mendeleev's?
It is organised by atomic number
It is organised by the properties of elements

8
1
18
7
26
Why do elements in the same family have the same physical and chemical properties?
Similar atom size
Similar electron configuration
Similar electronegativites
Similar number of neutrons
27
What portion of the periodic table below is highlighted?
Lanthanides
Nobel Gases
Transition Metals
Nonmetals
28
Why did
Mendeleev
leave gaps in the periodic table?
Because he thought there needed to be gaps
Because all of the elements had not been discovered
Because he thought it gave more space
Because he thought there were elements that fit the pattern
