For the noble gasses, you get D, but metals are basically everywhere in the periodic table...
Answer:
Physical property: Any characteristic that can be determined without changing the substance's chemical identity. Chemical property: Any characteristic that can be determined only by changing a substance's molecular structure.
Explanation:
Physical properties are something that is reverseable or has no change visible. Chemical properties are something that is NOT reverseable.
Chemical: Gas forming or Color Changing. (ETC.)

Answer:
The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons.
Based on the wave model of light, physicists predicted that increasing light amplitude would increase the kinetic energy of emitted photoelectrons, while increasing the frequency would increase measured current.
