The positive sub-atomic particle in the nucleus of an atom.
What is a proton?
These are made up of two or more atoms bonded together.
What are molecules?
This is the number that tells us how many protons are in an atom's nucleus.
What is the atomic number?
This is the resource we use to organize atoms/elements in a way that helps us understand their structure, behavior, and size.
What is the periodic table?
What is a neutron?
This molecule is made of two hydrogen atoms and one oxygen atom.
What is water/H20?
This is the first element on the periodic table with only one proton in the nucleus.
What is hydrogen?
This makes up 99% of an atom's volume (space).
What is nothing/empty space?
This is what we call the area outside of the nucleus where the negatively charged particles fly around.
What is the electron cloud?
That is how many Carbon atoms are in CO.
What is 1?
This is how many electrons gold has. 
What is 79?
This makes up 99% of an atom's mass.
What is the nucleus?
This is how many electrons would be in the first shell of a Carbon atom, which has an atomic number of 6.
What is two?
This is a molecule that is very large with repeating molecules?
What is a macromolecule?
This is how many neutrons Boron has. Boron has an atomic number of 5 and an atomic mass of 11.
What is 6?
What is 8?
This is how many electrons would be in the third shell of a Silicon atom, which has an atomic number of 14.
What is 4?
This is what atoms share in order to become bonded together in a molecule.
What are valence electrons? (electrons is acceptable)
This is the number that represents the total number of protons and neutrons in an atom.
What is the atomic mass/weight?
This is a substance with only one type of particle making it up.
What is a pure substance?
