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: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
