Terminology
The transfer of thermal energy through moving fluids.
What is convection?
The inner part of an atom that contains the proton and the neutron.
What is a nucleus?
The mass of an electron
What is essentially zero?
Anything that takes up space (has a mass).
What is matter?
Atomic numbers of an atom are always the same as the number of this subatomic particle in an atom.
What are protons?
When a nonmetal creates a compound with a metal, they form this kind of bond.
What is an ionic bond?
The particles that have a positive charge and are found inside the nucleus.
What are protons?
The unit that the mass of an atom is measured in.
What are atomic mass units (amu)?
The form energy takes when it leaves a radioactive atom.
What are gamma rays?
Carbon's atomic number
What is 6?

What is barium?
When something is dissolved in a liquid. This is not a solid, liquid, or a gas.
What is an aqueous solution?
The particles that are negatively charged and found outside the nucleus.
What are electrons?
A neutron's atomic mass.
What is 1?
The measurement of the average speed of a group of particles.
What is temperature?
The number of electrons in an unchanged helium atom.
What is 2?
The positively charged atom in a compound.
