2. Only one of these states is true. Which one is it? (6.P.2.1) * OTwo atoms of the same elements can have different properties.
Non-living things are made up of elements, but living things are not.
Something can be made out of atoms even if it is not matter.
O Anything that is matter has mass and volume.

I believe that the answer is: "Anything that is matter has mass and volume."

Explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
