This is the basic unit of a chemical element
What is an atom?
A difference in these two things causes an atom to become charged
What are protons and electrons?
Atoms with the same amount of protons but different amount of neutrons.
What are isotopes?
Also known as the planetary model
What is the Bohr Model?
An electron is this much smaller than protons and neutrons.
What is 1,840 x smaller?
A carbon atom with 10 electrons will have this charge
What is -4?
The number of protons in an atom of a particular element
What is atomic number?
The symbol for an atom with 6 protons and 7 neutrons
What is carbon-13?
This experiment was performed by Rutherford and his companions to determine that atoms are mostly empty space
What is the Gold Foil Experiment?
Water displacement, used for finding the volume of irregularly shaped objects, is also known as this philosopher and scientist's principle
Who is Archimedes?
When an atom gains an electron, it becomes this type of ion
What is anion?
Subtracting the atomic number from the mass number of an isotope will lead to this number
What is number of neutrons?
This law states that matter cannot be created nor destroyed.
What is the Law of Conservation of Mass?
The region of space where an electron is likely to be found
What is the cloud or orbital?
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?
You will find this many electrons on the 3rd ring of the Mg2+ Bohr Model.
What is 0?
This Greek word means "uncuttable" or "indivisible"
What is atomos?
This property of matter is intrinsic, meaning it does not change no matter how much or how little of the item you have. It is mass per unit volume.
What is density?
This scientist believed that atoms were blobs of positive matter with electrons spread throughout.
Who is JJ Thomson?
Boiling point, melting point, and density are an example of this
What are physical properties of matter?
Zinc bonds by giving away two electrons; therefore this is the number of electrons zinc typically has
What is 28?
1/12th the mass of Carbon-12
What is amu (atomic mass unit)?
Heisenberg has proposed electrons move as these.
What are waves?
These two scientists are credited for the most up-to-date model of the atom.
Who are Schrodinger and Heisenberg?
