The electrons, specifically the valence (outer shell) electrons.
There are quantum numbers that describe the location of electrons, if that is what you mean.Answer: by analyzing its interactions with another particle
Electron
Virion
The electron configuration of an atom determines how it behaves when it comes into contact with another atom.
Elctrons farthest from the nuecleus
A quark is a kind of subatomic particle, and 3 quarks makes up another subatomic particle (a baryon). A quark and an anti-quark make up another kind of sub-atomic particle, (a meson).
The atom is made up of several subatomic particles.The atom is made up of several subatomic particles.The atom is made up of several subatomic particles.The atom is made up of several subatomic particles.
A nucleon.
I think you mean "quark" (used to classify hadrons)
An antiparticle is a subatomic particle corresponding to another particle with the same mass, spin and mean lifetime, but with charge, parity, strangeness and other quantum numbers flipped in sign.
The number of protons in an atom determines the identity of the element.See these two related questions for more information:[http://wiki.answers.com/Q/What_is_the_atomic_number_and_what_does_it_tell_you_about_the_number_of_protons_in_an_atomWhat is the atomic number and what does it tell you about the number of protons in an atom?]and[http://wiki.answers.com/Q/How_do_you_find_the_number_of_protons_and_electrons_and_neutrons_in_an_atomHow do you find the number of protons and electrons and neutrons in an atom?]
A proton is a positively charged particle in the center of an atom. A neutron is another particle in the center of an atom that has no charge, but still has mass. Each particle, sometimes called a subatomic particle, has a mass of one AMU. The sum of these is the mass of one atom of an element. Electrons, the particles orbiting the nucleus, where protons and neutrons reside, are not taken into account in massing because they are so small.
They pass from particle to particle by vibrating the particle. When the particle touches another particle, it transfers the sound energy to that particle. Hence the Sound Wave.
