Why was Niels Bohr’s atomic model superior to all the earlier models? A.
It proved that the atom was indivisible and therefore the smallest unit of matter.
B.
It showed how the electron could orbit the nucleus without falling into it.
C.
It was the first to show that the atom had no net charge.
D.
It used wave behavior to explain the positions of electrons around the nucleus.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
