What are the properties of subatomic particles?
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons

Are elements the smallest type of substance?
Elements are the simplest type of chemical. An element is composed of atoms. Atoms in turn are composed of subatomic particles. However, all substances are composed of atoms, and there are no substances composed only of subatomic particles - at least, not on Earth. It is believed that there exist neutron stars composed only of neutrons. In that situation, you could say that the neutron is the smallest type of substance.

Is there a possibility of breaking an element?
Whew, I suppose it depends on what you define as breaking (assuming you are talking about chemical elements). If you have a single piece of elemental iron in solid form, you can break it into two pieces of elemental iron, although it is still an element. At one time, an atom was considered to be the smallest part of an element and could not be changed. However, that is only partly true. With radioactive decay, one element can be transformed into another. For example, Uranium 238 can undergo alpha decay and essentially be broken into Thorium 234 and a Helium ion. Particle Accelerators can be used to "smash atoms" that otherwise wouldn't spontaneously undergo radioactive decay. There are a number of subatomic particles including protons, electrons, and neutrons, but also additional smaller constituent particles of each of those.
Asked in Xenon
Can you break xenon?
It depends on what you mean by "break". Xenon is a monatomic gas so you aren't going to have any molecular bonds to break in the gas. Most Xenon is composed of stable isotopes so it doesn't much 'break" by radioactive decay. You could bombard it with nuclear particles and cause it to either absorb them and "break" by being transformed into a heavier element, or absorb to become radioactive and then "break" by decay, or fission to produce lighter elements (this is the most difficult since a lot of xenon isotopes are such good neutron absorbers)

Asked in Physics
Light is made of what kind of particles?
You cannot classify the phase of matter of light. The particles of light are much different than the particles of ordinary matter. At a large level, if we take the measurements, the light is a transverse wave carried by disturbances in an electric field and a magnetic field, each in perpendicular oscillations to each other, and each perpendicular to the travel of the wave. At the smallest level possible, there is a smallest piece of which you could call light. These are called photons. They are also the force carrier particles of electric and magnetic forces. These particles have zero rest mass, but they have an effective mass when in motion at the speed of light

If you know the name of a substancehow can you find out whether if is an element?
all of the 117 known elements (as of 2008) are in the "periodic table" of elements. If the name (or Latin abbreviation) of the substance is listed there, it is an element. Plato is one of the people credited with examining whether things could be reduced to the smallest particles that retained its properties (it took me many years to figure that one out). A table with the common names (instead of the Latin abbreviations) is in one of the links below.
