2. the smallest unit of matter that still has the properties of an element
3. describes a bond or molecule where electrons are shared unequally, creating partial charges
6. the ability to do work or cause change, often involved in making or breaking bonds
9. an atom or group of atoms that has gained or lost electrons and has a charge
11. a substance formed as a result of a chemical reaction
15. a measure of how strongly an atom attracts electrons in a bond
16. a type of bond formed when one atom transfers electrons to another
17. the arrangement of atoms in a molecule, including bond angles and shape
19. a type of bond formed when two atoms share electrons
20. a force that holds atoms together in a molecule or compound
21. a type of bond found in metals where atoms share a sea of electrons

1. describes a bond or molecule where electrons are shared equally between atoms
4. a type of reaction where one element takes the place of another in a compound
5. a chemical reaction where one compound breaks down into simpler substances
7. a process where substances change into new substances with different properties
8. a chemical reaction in which a substance reacts with oxygen and releases energy as heat and light
10. a chemical reaction where two or more substances combine to form one product
12. a substance made of two or more different elements chemically combined
13. a starting material that takes part in a chemical reaction
14. two or more atoms bonded together that act as a single unit
18. the number of electrons an atom can share, lose, or gain when bonding
