3. how well an atom attracts shared/bonded electrons towards its nucleus.
4. electrons, the electrons an atom has on its outermost (highest) energy level.
6. number, the total of the number of neutrons and protons in an atomic nucleus.
7. theory, theory that all things are made of tiny (smaller than microscopic) particles.
10. compounds, Composed of cations and anions (must have metal and non-metal).
12. reactions, the process in which chemical bonds are broken and/or formed
13. A subatomic particle that has no charge and that is found in the nucleus of an atom. glue together protons in the nucleus.
14. number, Number of protons in an atom. identifies the element. periodic table is organized by this mass
16. A substance made up of atoms of two or more different elements joined by chemical bonds.
19. A negatively charged particle that is found outside the nucleus of an atom. bonding & reactions & releases energy.
20. bonds, element with much higher electroneg ends up stealing e-

1. A homogeneous mixture of two or more substances.
2. radius, Describes the size of an atom.
5. energy being released (feel hot).
8. energy absorbed (feel cold).
9. area, When the surface area of the reacting particles is increased, the number of collisions is increased, which intern causes a reaction rate increase.
11. bond, atoms that share the same amount of electrons.
15. energy, energy required to initiate a chemical reaction.
17. A subatomic particle that has a positive charge and that is found in the nucleus of an atom. identifies element (atomic number)
18. An increase in temperature increases the average kinetic energy of the particles, which causes more collisions and ultimately an increase in the rate of reaction.
21. charged particle that result from gaining or losing electrons.
