The name of horizontal rows on the Periodic Table.
What is periods?
100
The amount energy required to remove an electron from an atom.
What is ionization energy?
100
The classification of most elements on the Periodic Table.
What is metal?
100
The element located in period 1 and group 1. It has it's own family, and makes up the Sun.
What is hydrogen?
200
The arrangement of the FIRST periodic table.
What is based on similar properties (law of octaves)?
200
The name of vertical columns on the Periodic Table.
What is families/groups?
200
The order of oxygen, nitrogen, and carbon based on increasing ionization energy.
What is C < N < O. (Ionization energy increases from left to right across a period.)
200
The group of elements that share properties of both metals and nonmetals.
What is metalloids?
200
The element located in period 5 group 15. This element use to be used by Egyptians to make black eye make-up.
What is antimony, Sb?
300
The father of the Periodic Table, he is credited with arranging the first Periodic Table of Elements.
Who is Mendeleev?
300
The family that is most stable (unreactive) in its natural state.
What is the noble gases?
300
The order of iodine, astatine, and bromine based on decreasing atomic radii.
What is At > I > Br? (Atomic radius increases down a group on the Periodic Table.)
300
A property/characteristic of a metal.
What is conductor, shiny, reacts with acid, hard? (Any answer listed will be accepted.)
300

What is the place where metalloids can be located?
400
The order of sulfur, arsenic and fluorine based on increasing electronegativity.
What is As < S < F? (Electronegativity increases from left to right and decreases top to bottom.)
400
The name of the elements listed from groups 3-12.

What is period 6 and group 14?
500
The discovery made by Henry Moseley, which in turn caused the Periodic Table to be rearranged.
What is the discovery of the proton?
500
The side of the Periodic Table where most of the gases are located.
