1. able to be drawn into a thin wire.
2. the number of joules needed to remove the most loosely bound electron from an atom.
3. the size of an atom.
4. a measure of how well an atom attracts electrons.
5. able to be shattered easily when struck.
6. the temperature at which a substance goes from a liquid to a gas.
7. able to be hammered into a thin sheet.
8. the mass per volume ratio of an element.
9. the temperature at which a substance goes from a liquid to a gas.
10. the shininess of an element.
11. able to allow electrical current to flow through.

Explanation:

1. Ionization Energy is defined as the energy required to remove the most loosely - bound electron from an atom.
2. Atomic radius is a measure of the size of an atom.
3. Electronegativity is a measure of how well an atom attracts electrons.
4. Boiling point is the temperature at which a substance changes from a liquid to a gas.
5. Density is the mass per volume ratio of an element.
6. Boiling point (repeated from 20, but it's the correct term for the given definition).

Answer:

1. Ionization Energy
2. Atomic radius
3. Electronegativity
4. Boiling point
5. Density
6. Boiling point
