What are quarks and leptons?
The type of reaction required to convert an atom to an ion.
What is a chemical reaction?
Named after this chemist, Da or Unified Atomic Mass Units are used to measure how large an atom is by adding the individual masses of its particles.
Who is John Dalton?
This form likes to take on the shape of its container, though it does have a definite volume.
What is a liquid
Two or more different elements that are physically combined without being bound together
What is a mixture
Protons and neutrons are found in this centrally located region of the atom, while electrons are found in the atom’s orbits
