h. atoms are mostly empty space surrounded by electrons
i. positively charged subatomic particle that gives elements their identity.
j. the average mass of all the isotopes of an element.
k. negatively charged subatomic particle that gives elements their reactivity.
l. neutrally charged subatomic particle that adds mass to the element.
m. elemental particle of matter - up, down, charm, strange, bottom, top
n. region of energy levels outside of the nucleus where electrons may be found
o. model of an atom with electrons embedded inside a positive sphere

Explanation:

1. The Law of Conservation of Mass states that matter is neither created nor destroyed, only changed, so it matches E.
2. The Plumb Pudding Model is a model of an atom with electrons embedded inside a positive sphere, matching O.
3. The Nuclear Atom Model holds that atoms are mostly empty - space surrounded by electrons, matching H.
4. The Electron Cloud Model describes the region of energy levels outside of the nucleus where electrons may be found, matching N.
5. A quark is an elemental particle of matter - up, down, charm, strange, bottom, top, matching M.
6. A proton is a positively - charged subatomic particle that gives elements their identity, matching I.
7. An electron is a negatively - charged subatomic particle that gives elements their reactivity, matching K.
8. A neutron is a neutrally - charged subatomic particle that adds mass to the element, matching L.
9. The atomic number is the number of protons (p+) or electrons in a neutral atom, matching F.
10. The mass number is not among the given definitions.
11. An isotope is an atom of an element that has the same number of protons but a different number of neutrons, matching G.
12. Isotopic Notation is a written notation showing atomic number, mass, name and or symbol of elements, matching C.
13. Natural Abundance is the percentage of each isotope of a single element found in nature, matching A.
14. An atomic mass unit (amu) is one - twelfth the mass of one carbon atom, matching D.
15. The average atomic mass is the mass of all isotopes of an element as measured by the percentage and mass of each isotope, matching B.
