What in the world is not chemistry

Chemistry concerns matter: how atoms are structured, how they bond, how substances interact with themselves and other substances. Anything smaller than subatomic particles and you're in the realm of physics. In the macroscopic world; how matter moves is the realm of physics, how matter forms living structures is now biology. How biology counts and performs calculations is math. I like to think of chemistry as the bridge between many things.

Chemistry cannot account for things like Young's double slit experiment, or waveforms, quantisation of photons, the Electomagnetic effect, quarks, strings etc. The list is endless.

Also, on a macro scale, chemistry cannot account for phase changes, such as water to steam.

Explanation:

Photons, gluons and gravitons (which are bosons) do not take up any space and have no mass. They do not participate in chemistry which involves only electrons.

Explanation:

a is the correct answer

you need to have a picture of the atom that way we can answer it
