Anti-matter. Antimatter.
Anti-particles. In the case of the (normal negatively-charged) electron, the anti-particle has a specific name; the positron. Since normal particles are the building blocks of matter, a collection of anti-particles are termed "anti-matter".
A positron is a fundamental particle because it does not consist of smaller particles, which would make it a composite particle. Fundamental particles can still decay or change identity however, but they have no (at least at this point) discernible internal structure. A proton on the other hand is a composite particle; it has an internal structure and consists of a mixture of gluons and quarks (which both are fundamental particles).

Yes.
Yes. Atoms are made of electrons (which are fundamental particles) and also protons and neutrons (both of which are baryons, made up of three quarks each; quarks are also fundamental particles).

Solute particles must be attracted to solvent particles because they are opposites, and as everyone knows opposites always attract.
opposites attract. the particles are attracted to the positively charged particles.

Not all of them are; the only direct subatomic part of the atom that is fundamental is the electron (which is a type of lepton.) Only particles made up of no smaller parts are called fundamental particles. For example, the proton (just like the neutron, except with a small difference) is not a fundamental particle because it is made of quarks, which are fundamental particles.

They are fundamental particles.
There can be beams of any fundamental particles.
The most fundamental law about charged particles is that like charges repel and opposite charges attract.
Yes.
An electron is believed to be a fundamental particle. There are no other particles in it.
