Answer 1

Column A:

1. products - g. the substances after a chemical reaction occurs
2. reactants - b. the substances before a chemical reaction occurs.
3. covalent bond - a. a force that holds atoms together by sharing electrons
4. electronegativity - d. a value that describes the relative strength with which an atom of an element attracts electrons to itself in a chemical bond.
5. ionic bond - c. a force that holds oppositely charged atoms (or groups of atoms) together
6. polar covalent bond - e. a force that holds atoms together by unequally shared electrons
7. valence electrons - f. the electrons in the outermost orbitals of an atom
