True or false? (a) The photon emitted in an n = 3 to n = 2 transition in the H atom has a lowerfrequency than the photon for an n = 2 to n = 1 H-atom transition. (b) The groundstate energy ofHe is about 4 times the ground-state energy of H. (c) yis zero at the nucleus for all H-atomstationary states. (d) For the ground state of the H atom, y2 is a maximum at the nucleus. (e) Themost probable value of the electron–nucleus distance in a ground-state H atom is zero. ( f ) Thesmallest allowed value of the atomic quantum number n is 0. (g) For H atom stationary stateswith l = 0, yis independent of qand f. (h) For the H-atom ground state, the electron is confinedto move on the surface of a sphere centered around the nucleus. (i) For the H-atom ground state, the electron is confined to move within a sphere of fixed radius.
A hydrogen isotope separator contains positively ionized hydrogen H^1, with isotope of hydrogen, Deuterium D^2, and other heavy particles, and the ions were released in a potential difference of 200 Volts. The strong magnetic field of 1.4x10^-2 Tesla (out of the page), bends the ions and Deuterium is collected on separate ionic trap as shown in the figure. (Masses MH1=1.67x10^-27 kg, MD2 = 2* MH1, Q(H1, D2) = 1.6x10^-19 C) What are the velocities of the Deuterium when exiting the plates, in unit of 10^5 m/s?
