Total questions: 20
Worksheet time: 17mins
Which scientist, in 1869, was the first to organize all the known elements into a a periodic table?
John Dalton
J.W. Dobereiner
Dmitri Mendeleev
Lothar Meyer
When creating his Periodic Table, Mendeleev organized the elements primarily by _________________, but then made changes based on the pattern of properties shown by the elements.
atomic number
atomic weight
number of neutrons
electron configuration
Mendeleev left some blank spaces in his Periodic Table. What were those blank spaces for?
The noble gases fit into those spaces
He thought elements would be discovered to fit into those spaces
He discovered many new elements and needed places to put them
He left spaces in case he needed to move some elements
Our current Periodic Table is organized by increasing __________________.
atomic number
atomic mass
metal properties
number of neutrons
In the modern Periodic Table, elements with similar properties are typically found
in the same period
in the same group
in the same block
in diagonals
Metals are typically found in which area of the Periodic Table?
To the left of the stair step
Along the stair step
To the right of the stair step
In the A groups only
The representative elements are found in groups
1A through 8A
3B through 12B
along the stair step
the bottom two rows
The elements in column 2 (group 2A) are called the
alkali metals
alkaline earth metals
halogens
noble gases
The halogens are found in
Group 1A (column 1)
Group 2A (column 2)
Groups 3B-12B
Group 7A (column 17)
