Question

calculate the wavelength ina ngstrom of photon that is emitted when an electron in bohr orbit n = 2 returns to the orbit n = 1 . the ionization potential of ground state of hydrogen atom is 2.17 * 10 ^ -11 erg / atom​

Answer 1

Answer:

E2-E1= -2.17*10^-11 [1/4-1/1] erg

n1=1. , n2=2.

Explanation:

hc/∆E=6.62×10-27erg
