Answer to Question #50822 in Atomic and Nuclear Physics for Saktesh Mahapatra

1)Assume that the electron in He+ ion is excited to the second orbit (n = 2).Calculate the following: I) the radius of the orbit. ii)the velocity of the electron. iii)the potential energy of the electron. iv)the kinetic energy of the electron. [HINT:use equations derived for hydrogen atom] 2) (a) explain the shapes of 1s and 2ps orbitals of an atom with one electron. (b) calculate the de Broglie wavelength of Li+ ion, if it moves with the velocity of 2 * 10^4 m S^-1. assume that the mass of Li+ ion is equal to two mass of Li atom.
