Large crystals from water solutions usually form from very rapid cooling.

Which factor is likely to impact the possible number of compounds ?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released
