An atom is a nucleus surrounded by several electrons. The nucleus is made of protons and neutrons; these can be further subdivided into quarks. As for dark matter, no one knows what it is. The only evidence for dark matter is the fact that the "light matter" (the stuff we can see in space) isn't nearly enough to create enough gravity to hold the universe together. It could be anything that has mass and isn't directly observable - white dwarves, black holes, bits of rock, as-yet-undiscovered kinds of fundamental particle, ... It could be a bit of each. Given that space is only illuminated in small patches where the stars are, it's not at all surprising that there appear to be things we can't see. In fact, dark matter is so elusive that in recent years some astronomers have begun to doubt whether it even exists, saying that maybe the general theory of relativity needs to be modified to add more gravity over larger distances. So dark matter could be made of atoms, like light matter - it could be something quite mundane. Could atoms be made of dark matter? In other words, could dark matter consist of subatomic particles? If it did, then it would be made of atoms (because nothing else is stable and made of subatomic particles).
No. An element is a group of the same kind of atoms. Compounds and mixtures contain different kinds of atoms, and thus, different kinds of elements.However, there are several things that are not made up of atoms. This includes light, different kinds energy, neutron stars, black holes... and the mysterious dark matter. The Universe contains at least 5 times as much dark matter, than atoms and other kinds of known matter.
It is called dark matter. Dark matter is undetectable and invisible.
Probably not. Dark matter is not believed to concentrate well in or around masses the size of stars. But it does concentrate well around galaxies and clusters of galaxies. Most of the mass of a galaxy like ours is believed to be in a sphere of dark matter in the galaxy's spherical halo.
Mainly that dark matter interacts with dark matter and with normal matter via the gravitational force; and that it DOES NOT interact with normal matter via any other known force. Or, if there is any interaction, it does so to such a small extent that it hasn't been possible to detect this so far.
There's no such thing as a "dark matter microscope." The whole point of dark matter is that it doesn't interact with electromagnetic radiation... if it did, it wouldn't be dark matter.
Atoms make up most matter around us. In the Universe in general, it seems that atoms make up about 4% of the mass of the Universe. The remainder of the Universe mass is dark matter and dark energy - both of unknown composition.
Components of the universe include dark energy, dark matter, luminous matter, and other compounds that are non-luminous. Sub-components include photons, atoms, neutrinos, and dark matter.

Presumably that refers to matter that is made up of atoms. Most matter in your everyday life is made up of atoms, but in our Universe, there is about 5 times as much matter that is NOT made up of atoms - the so-called dark matter.
No. Whatever the stuff is, its sole effect is gravitational.

Yes.

Not really. In part, this depends what you include in "everything". Most of the normal matter around us is made out of molecules. This includes solids, liquids, and gases. But please note that:* Some matter consists of individual atoms. "Molecules" are understood to have 2 or more atoms in a group. This includes most of the matter in stars - there it is too hot for the atoms to group to molecules.* Empty space is not "made up of" either atoms or molecules.* For every kilogram of normal matter in the Universe, there are at least 5 kilograms of some strange "dark matter". Nobody really knows what it is made of, but it's definitely not atoms or molecules.* Then there is the even stranger "dark energy" - there's even more of that in the Universe.* Light is made up of photons, not molecules or atoms.
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
Dark matter is all around us, inside and out, is what holds the forces of gravity together, keeps it from flying apart.
