Why do electrons enter the 4s orbital before entering the 3d orbital?
o a. because the 3d orbital is at a lower energy level
ob. because both the 4s and 3d orbitals are at the same energy level
o c. because the 4s orbital is at a lower energy level
od. because the 4s orbital is at a higher energy level

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
