In the Bohr model of the atom, the electrons are considered to be particles moving in specific and discrete orbits. a. True
b. False

True

Explanation:

Bohr proposed an atomic model in which;

the electrons found in an atom can only occupy orbits for which the angular momentum is quantized, which results in discrete values of energy level. the electrons in such stationary state or ground state emits no light, but if an electron jumps to a lower state, it emits a photon whose energy equals the difference in energy between the two states.  

Gas is all around us which means that the atmosphere
