Express the speed of the electron in the bohr model in terms of the fundamental constants (me, e, h, e0), the nuclear charge z, and the quantum number n. evaluate the speed of an electron in the ground states of he1 ion and u911. compare these speeds with the speed of light c. as the speed of an object approaches the speed of light, relativistic effects become important. in which kinds of atoms do you expect relativistic effects to be greatest? slader
