Found that matter can be split or cut into pieces multiple times.

Who is Democritus?

100

A subatomic particle with a negative charge.  It's quantity is determined by atomic number.

What is an electron?

100

The distance between the outermost energy level and the nucleus of an atom. (Size of an atom) 

What is atomic radius?

100

These represent electrons with a specific spin in orbital notation.

What are arrows?

100

This type of bond has a relatively large difference in electronegativity values.

What is an ionic bond?

200

He used the findings of many other scientists to form his own atomic theory.

Who is John Dalton?

200

This subatomic particle's quantity involves the difference of the atomic mass and atomic number.

What is a neutron?

200

How much energy is required to discharge an electron.

What is ionization energy?
200

This type of notation is written in numerical order, not fill order.

What is electron configuration?

200

This type of bond has almost no difference in electronegativity values.

What is a nonpolar-covalent bond?

300

They burned a diamond to find that the same gas was produced when burning coal.

Who are Lavoisier and Davy?
300

Oxygen has 8 of these positively charged subatomic particles in one atom.

What are protons?

300

The tendency for an atom to attract electrons.

What is electronegativity?

300

The spaces in orbital notation where you put the arrows.

What are orbitals?

300

This is the part of a chemical reaction that runs out first, determining the maximum amount of product that can be made.

What is the limiting reactant?

400

He developed the plum pudding model.

Who is JJ Thompson?

400

The difference of the expected mass of an atom and the actual mass of an atom.

What is mass defect?

400

When you start a new one of these, a new main energy level is added.

What is a period?

400

The letters in orbital or complete electron configuration notation.

What are sublevels?

400

In a Lewis Dot Structure, these are represented by dots placed around an element.

What are valence electrons?

500

He said that there are elements yet to be discovered.

Who is Mendeleev?

500

Often represented by Helium, this particle has an atomic mass of 4.

What is an alpha particle?

500

This decreases as you move across a period, but spikes up when you start a new period.

What is atomic radius?

500

The big number in front of the letters in orbital or complete electron configuration notation.

What are main energy levels?

500

This number tells us the number of atoms that are present for a substance in a chemical equation.
