how do i do the theoretical energy level transition n1 to n2 ?

Answer 1

For H-like atom (single é system) n=1 7=2 n=3 n= 4 According to Bohr atomic model, we know that myy = nb भा 1.Ze2 = mv ² ③ 은 Kesto Kinetic energy of e = 1 mv2 ...P.E. of é = -bl. Ze2 (For two charge 3 Attor 2 ♡ G system i total energy of election = K.E+PE

After solving we get total energy of election = Date: page: Exotal = - 13.6 2% zev where a= atomic No - n = no of é where -18 Etotal = -2.18x10 X2²%² Joule Energy for na .: Ei= - 13.6.7² 1,2 er 6 D ع E2 = -13.62% 2 ex For transition ne the DE - E₂ - G ==13:6772 - (–13.627 Je – 13.62² for H-atom, Z=1 DE = 1306 for numerical value, we can put they put the value of the hatev ni and ne.
