Let us admit that the proton is not a point, but has a uniform spherical charge distribution of r (where r is much smaller than bohr's radius), find (a) how this pertubation can be approached, and (b)how much the 2p and 2s electronic shells will be shifted to the first approach? (c) if the s shell exhibits a small energy separation of its layers, which will be the reason?

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
