Answer 1

Here is the correct matching of terms from Column A to their definitions in Column B:

1. products: f. the substances after a chemical reaction occurs
2. reactants: d. the substances before a chemical reaction occurs
3. covalent bond: a. a force that holds atoms together by sharing electrons
4. electronegativity: g. 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: b. the electrons in the outermost orbitals of an atom
