1.	a 12.9 electron volt beam of electrons is used to Bombard gaseous hydrogen at room temperature at which level the hydrogen atom would be excited??
Answer» ergy of ELECTRON in the ground state of hydrogen atom = -13.6eV when beam of electrons of energy 12.9 electron volt Banbard hydrogen atom the energy of electron in the hydrogen atom, = EN = -13.6 + 12.9 = -0. 85eV now using, En = -13. 6/N^2 we get n^2 = -13. 6/En = -13. 6/0.85= 16 n =4
