Why doesn't an atoms atomic number correlate with how common the element is?

Helium has the atomic number 2 and is the second most common element. & #x200B; However, after that, the atomic number doesn't correlate to the elements abundance. The next most abundant is Oxygen, which has an atomic number of...

How does light pass through a transparent object, slow down, then speed up again?
I know that light is both a particle and a wave, and that the refractive index of a material is pretty much a function of its density. How then, does light interact with these particles (slowing them down) and keep a coherent beam/image?
