This scientist created the first accepted periodic table with columns and rows.
Who is Mendeleev?
100
The columns of the periodic table are referred to as:__________
What is a group or family?
100
These elements share the properties of metals and nonmetals.
What are metalloids?
100
This family of elements contain extremely reactive gases.
What is the Halogen family?
100
This term refers to the ability of an atom to attract electrons to itself.
What is electronegativity?
200
This scientist grouped elements together according to triads.
Who is Dobereiner?
200
The rows on the periodic table are referred to as:_____________
What is a period?
200
At room temperature, most elements are (solid/liquid/gas)
What is solid?
200
Which groups of the 1-18 columns on the periodic table are considered transition metals?
What are 3-12?
200
As we move across a period on the periodic table, the atomic radius (increases/decreases)
What is decreases?
300
This scientist confirmed that the structure of the periodic table was correct by verifying the progression of atomic numbers.

300
As we move down a group on the periodic table, the ionization energy (increases/decreases).
What is decreases?
400
This scientist left empty spaces in his periodic table for elements that would yet to be discovered.

400
All of the elements in a group of family have the same number of :______________
What is valence electrons?
400
An element that is very shiny, has the consistency of clay, and has one valance electron would be a (metal/metalloid/nonmetal)
What is a metal?
400
True/False: The noble gases are the most reactive family of elements on the periodic table.
What is false?
