This has a positive charge in the atom.
What is the proton?
Number of protons and neutrons in the nucleus of the atom.
What is the atomic mass?
When you cut a piece of paper
What is a physical change?
This state of matter has definite shape and volume and the particles are compact.
What are solids.
Combined substances that can be separated using physical processes
What is a mixture?
This has a neutral charge and is located in the atomic nucleus.
What is the neutron?
Protons and neutrons are found here.
What is the nucleus?
When you burn a piece of paper
What is a chemical change?
This form of matter flows to shape a container and the particles are far apart.
What is gas?
Mass and length are examples of these types of properties.
What are extensive properties?
This has a negative charge and is located outside the nucleus of a atom.
What is the electron?
The number 6 represents this in the image.

What is the atomic number?
What is the number of protons?
What is the number of electrons?
When an atom gains or loses an electron.
What is an ion?
This is an ionized substance that becomes highly electrically conductive to the point that long range EM fields dominate its behavior.
What is plasma?
The variable that is manipulated in an experiment.
What is the dependent variable?
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons
What is an isotope?
If Uranium has 92 protons, then it must have this many electrons.
What is 92?
The name for the process when a solid turns directly into a gas without becoming a liquid.
What is sublimation?
This form of matter flows with a constant volume and takes the shape of an container. Particles are less closely packed.
What is liquid?
The ratio of equivalent values having different units
What is a conversion factor?
An unstable nuclei of an atom emits a helium nucleus of mass to become a new element.
What are Alpha particles? or alpha radiation?
This is the atomic mass of an atom minus the atomic number
What is the number of neutrons?
The name for the process when a gas turns directly into a solid without going through the liquid phase.
What is deposition?
mass reactants = mass products
What is the Law of Conservation of Mass?
This is the number of sig figs in 0.002101
