This is the basic unit of a chemical element

What is an atom?

100

A difference in these two things causes an atom to become charged

What are protons and electrons?

100

Atoms with the same amount of protons but different amount of neutrons. 

What are isotopes?

100
The sum of protons and neutrons in the nucleus of an atom.
What is mass number?
100

Also known as the planetary model

What is the Bohr Model?

200

An electron is this much smaller than protons and neutrons.

What is 1,840 x smaller?

200

A carbon atom with 10 electrons will have this charge 

What is -4?

200

The number of protons in an atom of a particular element

What is atomic number?

200

The isotopic symbol for an atom with 6 protons and 7 neutrons

What is carbon-13?

200

This experiment was performed by Rutherford and his companions to determine that atoms are mostly empty space

What is the Gold Foil Experiment?

300

Water displacement, used for finding the volume of irregularly shaped objects, is also known as this philosopher and scientist's principle

Who is Archimedes?

300

When an atom gains an electron, it becomes this type of ion

What is anion?

300

Subtracting the atomic number from the mass number of an isotope will lead to this number

What is number of neutrons?

300

This law states that matter cannot be created nor destroyed. 

What is the Law of Conservation of Mass?

300

The region of space where an electron is likely to be found

What is the cloud or orbital?

400

This man's atomic theory was built on Democritus's and states that matter is made up of indivisible particles that carry certain properties. 

Who is John Dalton?

400

You will find this many electrons on the 3rd ring of the Mg2+ Bohr Model.

What is 0?

400

This Greek word means "uncuttable" or "indivisible"

What is atomos?

400

This property of matter is intrinsic, meaning it does not change no matter how much or how little of the item you have. Its units are mass per unit volume.

What is density?

400

This scientist believed that atoms were blobs of positive matter with electrons spread throughout. 

Who is JJ Thomson?

500

Boiling point, melting point, and density are an example of this

What are physical properties of matter?

500

Zinc bonds by giving away two electrons; therefore this is the number of electrons zinc typically has

What is 28?

500

1/12th the mass of Carbon-12

What is amu (atomic mass unit)?

500

Heisenberg has proposed electrons move as these.

What are waves?

500

These two scientists are credited for the most up-to-date model of the atom. 

Who are Schrodinger and Heisenberg?
