Q. What is ionisation potential energy?
For hydrogen atom the energy necessary to remove an electron from first orbit to its outermost orbit (n=∞) is 13.6-0 = 13.6eV. This energy is recognized as the ionization potential energy for hydrogen atom.
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
