5
What does the group number in the periodic table tell us?
How many protons an element has
How many electrons in outer shell
The elements mass
How many neutrons an element has
6
Which is a draw back of Mendeleev's periodic table
Could not assign a correct position for Hydrogen.
It was in order of relative atomic mass
He left gaps
7
What pattern did John Newland find in his periodic table?
He found a pattern of groups and periods
Each element was similar to the element eight places ahead
Each element was similar to the element six places ahead
He did not find a pattern
8
Why was Newlands’ periodic table not accepted by other scientists?
Elements were in groups that didn't match their properties
There was no clear pattern
He did not leave gaps
It had not been backed by other scientists
9
Why did Mendeleev leave gaps in his periodic table?
For elements that had not yet been discovered
To separate elements with different properties
He did not know how to fill the gaps
