1. (a) I‚ III‚ and IV are correct. II is not correct. To explain III‚ de Broglie’s equation states l = h/(mv)‚ so nl = nh/(mv) = 2pi(r). Where: l = wavelength‚ v = velocity of electron‚ n = some positive integer‚ r = distance of electron from center‚ m = mass of electron. Solve‚ get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing integer number (n). 2. (a) The first shell electrons in Lithium are
