Explanation: For neutral atom . No. of p = No. of e–
= 18 and
A = Z + No. of neutrons = 18 + 20 = 38
Which orbital of carbon can absorb photon but not emit it?
If wavelength of photon is 2.2×10^−11m, h=6.6×10^−34Js ,then momentum of photon is
The energy of a photon is given as △E╱atom=3.03∗10^−19 J atom^−1. Then the wavelength (λ) of the photon is.
Ratio of energy of photon of wavelength 3000 Å and 6000Å is
