When an electron in a 2p orbital of a particular atom makes a transition to the 2s orbital, a photon of approximate wavelength 646.3 nm is emitted. the energy difference between these 2p and 2s orbitals is: . 3.07 ã 10^â28 jb. 3.07 ã 10^â19 jc. 3.07 ã 10^â17 jd. 1.28 ã 10^â31 je. none of these

The energy difference between these 2p and 2s orbitals is

Explanation:

Wavelength of the photon emitted =

Energy of the photon will corresponds to the energy difference between 2p and 2s orbital = E

Energy of the photon is given by Planck's equation:

h = Planck's constant =

c = Speed of the light =

The energy difference between these 2p and 2s orbitals is

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

i dont know the answe
