An atom is made up of three particles called protons, neutrons and electrons. An atom is the most basic form of matter and can not be broken down any further. Protons and neutrons come together in the center of the atom to form the nucleus. Electrons orbit the nucleus.
- All atoms in the universe are made up of the same basic particles: the proton, the neutron and the electron. The different combinations of those particles combine to make different elements, which combine to make different molecules.
- Now to our knowledge today, atoms are made up of quarks (and gluons) and electrons, and these are the elementary building blocks. Now these elementary building blocks can be combined in different ways, building up different atoms.

Types Of Atoms
Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you.
Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.
Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.

We've covered some of those questions in the other parts of this thread.
Light is a wave, a quantum wave. Like all other quantum waves, it has an interesting particle-like side to how it behaves. Certain types of detectors will pick up 0, 1, 2,.... blips of light, but not say 1.3. That's just like counting particles. So we sometimes say that light is made of particles called photons, but we don't mean that there are little dot-like things in it.
Light can be compressed, like other waves. I'm not sure what you mean by 'reflected or absorbed into itself' but there are processes by which two photons are lost and their energy shows up in another form- say an electron-positron pair.
Light, like any form of energy, has some gravitational weight, but it's extremely small compared to other weights that are around.
I don't know how in English the different meanings came to be attached to the same word, 'light' . According to my dictionary, the one about stuff you see goes back to Indo-European 'leuk-' and the one for not being heavy goes back to Indo-European 'legwh-'.
