Which statement is correct? (5 points) a The gas particles in both containers have the same average kinetic energy because they have equal number of particles. b The gas particles in both containers have the same average kinetic energy because they have the same volume. c The average kinetic energy of the gas particles is greater in container A because it has a lower temperature. d The average kinetic energy of the gas particles is greater in container B because its particles move faster.

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.
