Question

Question 1: Which photon energies will excite the Hydrogen atom when its electron is in the ground state (Hint: there are 5 named on the simulator, though there are more Question 2: Starting from the ground state, press the L, button twice in succession (that is, press it a second time before the electron decays). What happens to the electron? Question Complete the energy mange values for the excited state the second orbital) of Hydrogen. Use the simulator to fill out ranges 2 and range 3. The election can be placed in the 1st orbital by manually dragging the electron or firing a L. ploton once when the electron is in the ground state. Note also that the electron will deexcite with time and so it may need to be placed in the 1st orbital repeatedly 1" Excited State Electron in H Range 1 Range 3 0 to 1.9 eV (Anything less than this energy will fail to excite the atom) Range 2 ete) to be Question 4: What is the necessary condition for Balmer Line photons ( H absorbed by the Hydrogen atom? NAP-Hwrogen Atom 3/5

questions 1, 2, 3, 4 please answer all of them.

Answer 1

SOLN 1

Energy required for two transitions

En = -13.6 (1/n1² - 1/n2²) eV

where n1= 1 ground state and n2 = 2,3,4 . .. . .

so 1st transition n1=1 and n2 =2

E1->2 = -13.6( 1-1/4) = -10.2 eV

for 2nd transition n1=1 and n2 =3

E1->3 = -13.6( 1-1/9) = -12.08 eV

for 3rd transition n1=1 and n2 =4

E1->4 = -13.6( 1-1/16) = -12.75 eV

for 4th transition n1=1 and n2 =5

E1->5 = -13.6( 1-1/25) = -13.05 eV

for 5th transition n1=1 and n2 =6

E1->6 = -13.6( 1-1/36) = -13.22 eV
