The cooling curve above shows how the temperature of a sample varies with time as the sample goes through phase changes. the sample starts as a gas, and heat is removed at a constant rate. at which time does the sample contain the most liquid?

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.

the answer is minerals.

im pretty sure its b
