### substance | particle | boson:

W boson
* are named after the weak force that they are responsible for.
+ W and Z bosons, Naming: Elementary particles
  * W bosons are named after the weak force that they are responsible for. The naming of the Z boson is still uncertain, although it is believed to have been the last particle on a list that a lab that named it was looking for. Weak force is what physicists believe is responsible for the breaking down of some radioactive elements, in the form of Beta decay. In the late '70s, scientists managed to combine weak force and electromagnetism, and called it the electroweak force.

Charged particle
* Shows the motion of a charged particle in an electro-magnetic field.
* are at the basis of all electricity.
* can disrupt computer memories.
* have a considerable influence on the surface properties of Galilean moons.
* leave marks as they cross photographic plates.

Chylomicron
* are atoms
  - mostly triglycerides
  - the largest and least dense
* enter lacteals and are carried away by lymph
  - the bloodstream and deliver their triglyceride to adipose tissue and muscle
* function primarily to transport dietary triglycerides from the intestines.

Coarse particle
* Some coarse particles have frictional strength
  - high strength
* can also make a substantial contribution in summer.
* come from sources such as wind blown dust and unpaved roads.
* consist largely of naturally occurring substances, particularly soil.

Colloidal particle
* are larger than molecules.
* are too small to be seen by the naked eye
  - with ordinary optical microscopes
* have an electric charge on their surface.

Deuteron
* are h
  - independent subatomic particles
  - major components of nuclei of atoms
* attract each other due to gravity.
* have combined mass of a proton and a neutron.

Dust particle
* reflect sunlight.
* suspend in air.

Elementary particle
* All elementary particles are either fermions or bosons
  - matter particles or force-carrying particles
* Every elementary particle is either a fermion or a boson.
* Most elementary particles carry electricity.
* Most elementary particles have mass
* appear as quantized oscillations of very small strings.
* are part of atoms
* have charge
  - no color
* possess an intrinsic quantum mechanical property known as spin.

Energetic particle
* Most energetic particles move from regions.
* Some energetic particles can have effects.
* leave a trail of ions in their wake.
* penetrate into the atmosphere and change the chemical constituents.

### substance | particle:

Fermion
* are highly territorial individualists
  - particles with half-integer spin
  - spin odd half integer, bosons are integer spin
  - the type of particles that make up the atom, ie electrons, protons and neutrons
* have half-integral spins
  - properties , such as charge and mass , which can be seen in everyday life
  - wave functions which are antisymmetric under the interchange of identical particles
* incude electrons , protons , neutrons.
* obey the exclusion principle.
+ Standard Model, Fermions: Basic physics ideas :: Relativity :: Matter :: Nuclear physics
  * Examples of groups of fermions are the proton and the neutron. Fermions have properties, such as charge and mass, which can be seen in everyday life. They also have other properties, such as spin, weak charge, hypercharge, and colour charge, whose effects do not usually appear in everyday life. These properties are given numbers called quantum numbers.
