Using the Bohr model, find the ionization energy of the ground He ion.

54.4ev

Explanation:

Using

E = - me⁴Z²/8Eo²h²n²

Where n= 1

Z= 1

h=6.6E-31Js

me= 9.1x 10-31kg

Eo=8.85E-12m-3 kg-1 s4 A2

So by substituting

E= -(9.1x 10-31kg)⁴x 1²/8(8.85E-12m-3 kg-1 s4 A2)² x (6.6E-31Js)² x 1²

So E= 54.4ev

spare some change and give it to the poor

explanation:

plz : ((

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
