Is this set of quantum numbers possible? n = 2, l = 1, ml = 0, ms = +1/2
Electron microscopes operate on the fact thatelectrons act as waves. A typical electron kinetic energy is100 keV (1 eV 5 1.602 3 10219 J). What is the wavelength ofsuch an electron? (Ignore relativistic effects.)
Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (), the magnetic quantum number (m), and the spin quantum number (m,) have strict rules which govern the possible values. Identify all allowable combinations of quantum numbers for an electron.

Express the speed of the electron in the Bohr model in terms of the fundamental constants (me, e, h, 0), the nuclear charge and the quantum number n. Evaluate the speed of an electron in the ground states of He+ ion and U91+. 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?
