Explanation:

1. The periodic law (j) states that when elements are arranged by increasing atomic number, there is a periodic repetition of their chemical and physical properties.
2. Representative elements (k) are in the s and p blocks.
3. Transition elements (l) are in the d block.
4. Alkali metals (a) are Group 1 elements (except Hydrogen).
5. Alkaline earth metals (b) are Group 2 elements.
6. A group (m) is a column in the periodic table.
7. A period (e) is a row in the periodic table.
8. Halogens (d) are Group 17 elements.
9. Noble gases (h) are Group 18 elements.
10. An ion (f) is an atom or bonded group of atoms that has a positive or negative charge.
11. Ionization energy (g) is the energy required to remove an electron from a gaseous atom.
12. The octet rule (i) states that atoms tend to gain, lose, or share electrons to acquire a full set of eight valence electrons.
13. Electronegativity (c) indicates an atom's ability to attract electrons in a chemical bond.

Answer:

1. j. periodic law
2. k. representative elements
3. l. transition elements
4. a. alkali metals
5. b. alkaline earth metals
6. m. group
7. e. period
8. d. halogens
9. h. noble gases
10. f. ion
11. g. ionization energy
12. i. octet rule
13. c. electronegativity
