This whole number represents the number of protons in the nucleus of a given element.
What is the atomic number?
100
These are the three types of elements.
What are metal, nonmetal, and metalloid?
100
It's no surprise that the man who created the periodic table had this element named after him.
What is Mendelevium?
100
All of the alkaline earth metals are in this group.
What is Group 2?
200
All of the members of this family have an oxidation number of +1.
What are the alkali metals?
200
This number is an average, by abundance, of the masses of all the isotopes of a given element.
What is the average atomic mass?
200
This type is the most electrically conductive.
What are the metals?
200
It probably wouldn't be smart to try to use this element to make you more intelligent. It was named after the physicist who came up with relativity and it is radioactive.
What is Einsteinium?
200
These two periods are the longest on the periodic table.
What are 6 and 7?

This grouping contains by far the most elements on the periodic table.
What are the transition metals?
300
This is the commonly used abbreviation for the element.
What is the atomic symbol?
300
This type is often used in computers because of its semiconductor properties.
What is "metalloid"?
300
This noble gas was not named after Superman's home planet.
What is Krypton?

What is period 1?
400
Members of this family can lose two electrons to form a +2 charge.
What are the alkaline earth metals?
400
Sometimes, this will also be included in the box for an element: a sequence of letters and numbers that describes the behavior of an element's negative charges.
What is an electron configuration?
400
Nonmetals are called this because they don't conduct electricity.
What is "insulator"?
400
This Group I element is unique on the periodic table. Its' name is indicative of its presence in the most abundant liquid in the human body.
What is Hydrogen?
400

What are Groups 2 and 3?
500
This family contains elements in all three states of matter at room temperature.
What are the halogens?
500
An element that has not been stabilized will have these two things in the box that differentiate it from stable elements.
What are a three-letter symbol and a mass in parenthesis?
500

What are metals?
500
This element was named after a planet which is no longer a planet.
What is Plutonium?
500
All of the elements in this group have 7 electrons in their valence shell when neutral, causing them to form a -1 charge when ionized.
