Question

Find the maximum amount of energy that can be absorbed by an electron in the hydrogen atom.

Answer 1

energ is when an electron absorb a photon it gains the energy of the phaton. Because an electron bound to an to can only have certain energies the electron can only absorb photon of certain energies. The formula defining the energy levels of a Hydrogen atomb are given by the equation: -- Eo 62 -19 where = 13.6ev (lev = 1.602x10 9 Joules) and n= 1, 2, 3, – – – soon. For example an electron in the ground state has an energy of - 13.6 ev. The second energy level is -3.4ev . They it would take t= -3.4er- (-13.6ev) = 10.2ev JO excited State. D e Formula to excite the exectron from the ground state to the first The energy of the emitted photon is given by Rydberg Epheten for for maximum energy nes and n o Eperm = fopen) Ephaton = to G-07 (=) where DILDO

Ephoton = 13.6ev This is an the maximum energes that can be absorbed by election in the hydrogen atom. Ans 13.6 evolt ev - electron volt. 08 = 13,6X1, 602 X10 19 Joules T = 2.2 110-18 Joules I ans ANS
