for each item in column a, write the letter of the matching item in column b.
column a

1. a combination of two or more components that retain their identity
2. the attraction of two atoms for a shared pair of electrons that hold the atoms together
3. a substance that is composed of atoms of two or more different elements that are chemically combined
4. a solution containing a substance that produces hydrogen ions (h+) in water
5. an atom that gains or loses an electron and is a charged particle
6. composed of two or more atoms held together by covalent bonds
7. a homogeneous mixture
8. the attractive force between two ions of opposite charge
9. the forces that hold the elements together in a compound
10. a solid homogeneous mixture
11. a solution characterized by the formation of hydroxide ions (oh )
12. the change of one or more substances into other substances

g. ion
h. ionic bond
i. mixture
j. molecule
k. solid solution
l. solution

Explanation:

1. A mixture is a combination of two or more components that retain their identity.
2. A covalent bond is the attraction of two atoms for a shared pair of electrons that hold the atoms together.
3. A compound is a substance that is composed of atoms of two or more different elements that are chemically combined.
4. An acid is a solution containing a substance that produces hydrogen ions ($H^{+}$) in water.
5. An ion is an atom that gains or loses an electron and is a charged particle.
6. A molecule is composed of two or more atoms held together by covalent bonds.
7. A solution is a homogeneous mixture.
8. An ionic bond is the attractive force between two ions of opposite charge.
9. Chemical bonds are the forces that hold the elements together in a compound.
10. A solid solution is a solid homogeneous mixture.
11. A base is a solution characterized by the formation of hydroxide ions ($OH^{-}$).
12. A chemical reaction is the change of one or more substances into other substances.
