1. Type of bond where electrons are shared unequally between atoms
4. The charge an atom would have if electrons were transferred completely
5. Set of relationships describing pressure, volume, temperature, and amount of gas
7. Reactant that runs out first and determines how much product forms
9. Comparison of actual yield to theoretical yield expressed as a percentage
10. Using balanced equations to calculate quantities of reactants and products
12. Type of bonding where atoms share electrons to become stable
14. Force that holds atoms together in a compound
16. Neutral particle found in the nucleus of an atom
17. Chemical equation with equal numbers of each atom on both sides
19. Principle stating matter cannot be created or destroyed in a chemical reaction
20. Positively charged particle found in the nucleus of an atom

2. Minimum energy needed to start a chemical reaction
3. Two or more atoms chemically bonded together
6. Electrons in the outermost energy level that are involved in bonding
8. Substance formed from the attraction between positive and negative ions
11. Attractions between molecules that affect physical properties like boiling point
13. Relationship showing pressure and volume are inversely proportional at constant temperature
15. Measurement of concentration defined as moles of solute per liter of solution
18. Energy required to remove an electron from an atom in the gas phase
