High albedo does not imply perfect scattering. White surfaces can be very rough and reflect light in all directions. Mirrors are smooth, so the scattering is nice and regular. The way mirrors are made is by covering a thin coat of silver with glass. Molten metals are very smooth, obviously.

Yeah, because it's made of a material that is extremely hard to smooth out. It's brittle. Metal can be molten and it naturally gets smoothed by gravity. You can jerk off a piece of chalk with sandpaper all you want, but it's not going to refine all those microscopic cavities that scatter light in random directions.

also, even if white surfaces can't show my face because the light travels in different directions, it should at least change color to the color of my face.
the fact that it keeps being white when you put something of another color next to it proves that white isn't unpolished mirror

White surfaces diffuse light by absorbing and re-emitting photons but does so evenly across all visible wavelengths, reflective surfaces like mirrors and metals have an electron shield that bounces photons along the normal of the surface causing them to have that clear reflection in the unaltered color as the inbound light.

Any sufficiently smooth surface will have a dull mirror like reflection as the return vector is similar but you can never polish a surface that absorbs light such that it has a clear mirror like reflection from any angle. You can get a very mirror like reflection at glancing angles due to the fresnel effect tho.

Metals form ionic and covalent bonds with nonmetals, as is the case in chalk. They typically form metallic bonds with metals, but even that isn't a rule, gallium forms covalent bonds with metals.

Two types of bonds, both specifically dependent on what is being bonded..

As long as the shared valency orbital totals a stable 8 electrons, who gives a fuck.

This. Fully reflective surfaces like polished metals have electromagnetic properties which repeal photons at the very top layer of atoms before they can enter the material at all.

Dielectric non conductive surfaces no matter how polished still have the photons travel into the top layers of the material get absorbed there and is scattered and remitted internally til it eventually find it's way out traveling in some direction other than that which it entered according to the sort of probability distribution >>16560529 shows. That's why you can't polish a white surface into a perfect mirror, if something appears white its not reflecting light; it's scattering light.

White things do exactly that. Stand next to a white wall under a sunny window and the light from your shirt will make the wall reflect that color.

The octet rule is also a simplified rule of a thumb. Boron and aluminium for example don't give a shit.

AlCl3 doesn't have an octet, if you followed
>muh octet
and
>muh ionic if metal and nonmetal
You'd come to the wrong conclusion that it must be an ionic compound where Al gives out one of its 3 valence electrons to each Cl. On the other hand, If you bothered to check the electronegativity difference (1,6, ionic bonds are typically 1,7 at the very least) and knew that aluminium is in the highly electron deficient group 3, you'd probably figure out that it has to have covalent bonds with only 6 valence electrons in Al.

I recommend trying to understand the underlying fundamental concepts instead of relying on simplifications.

the surface is a mirror (and some of the color change affect the color of the mirror), and some of the subsurface is also being reflected, and this is why polishing a human wouldn't be as reflective as a metal either

Can you “see” a mirror or do you just see your reflection? Because I can clearly see the pattern on the marble, so it’s clearly absorbing some of the light that falls on it.

How do bats use sound to navigate in the darkness? We'll get to that in a second, but what's even more important, why can't I just hit everything in front of me with my eyes closed and act like I am blind? Why am I not allowed to do this? What if I told them that I was preparing myself to become blind? Would that be a good enough reason to do this? I don't have ears good enough to capture vibrations that bounce off of walls, that's not even my fault.

Diffuse reflection. Exact mechanism varies with material, but in something like chalk the diffuse nature of reflection is largely due to subsurface scattering. Chalk is made of tiny transparent crystals calcite; a ray of light can enter the surface of chalk, be reflected by numerous crystal facets, and then exit the surface at a quasirandom angle

White surfaces aren’t like mirrorsS because they don’t bounce light back at you all neat. They kind of spread it around everywhere, like when you spill your cereal and it goes everywhere :3. Mirrors reflect light in a way that makes your reflection look clear, but white surfaces just send it all over the place like they can’t focus, kind of like how cats always knock things off tables for no reason
