A gas occupies a volume of 100.0 mL at 27.0C. At what temperature would the volume be 50.0 mL?

d.) circle motion requires a force to give it a centripetal acceleration.

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.

c. electrical charges of ionic bonds.
