### nucleon:

Proton
* All protons have the same charge, and all neutrons are neutral.
* Every proton always has an electron around it and every neutron is powerless
  - carries a definite positive electric charge, whereas neutrons are neutral
* abstracted by bases are labile and exchange rapidly with solvent protons.
* appear to be more complex, allowing a wide range of types of interaction.
* are a positively charged mass that is present in the nucleus which is the core of the atom
  - an essential and apparently stable build ing block of matter
  - baryons, formed by two up and one down quark
  - better for larger and more complicated shaped abnormalities of the brain
  - companies
  - corpuscles constituted in some unknown way and exhibiting a positive sign
  - elementary particles that are a component of all atoms
  - fixed in place and incapable of moving in any electrostatic experiment
  - found in the nucleus of the atom
  - heavier and take up less space
  - heavy particles made of three quarks
  - in atoms and the give a positive charge
  - known as baryons , which means that they are made of exactly three quarks
* are made of other particles called quarks
  - mass which move across the osmotic gradient
  - more 'complex' than their individual constituents
* are more massive than neutrons
  - photons or electrons, and so scatter less as they pass through tissue
  - nucleons
  - often the particles accelerated, because of their small mass and relative stability
* are part of atoms
  - nucleuses
  - parts of atoms with a positive charge
  - positive and electrically repel one another
  - relatively massive particles which carry a positive electrical charge
  - rockets
  - small and therefore hard
  - subatomic particles with a positive electrical charge
  - subatomic, positively charged particles, found in the nuclei of atoms
  - the positively charged particles found in the center of all atoms
* bear a positive electric charge.
* build up between the inner and outer membranes of the mitochondria.
* carry a positive charge, electrons have a negative charge, and neutrons are uncharged
  - neutrons carry no charge, and electrons carry a negative charge
  - positive charge, but neutrons are neutral, carrying no charge
* contain two up quarks and one down quark.
* contribute more to an atoms mass.
* decay into electrons, positrons, to neutrinos.
* deposit almost all of their radiation dose near the end of their tracks, where they stop.
* deposit their energy near the end of their path and have little lateral scatter
  - radiation dose differently
* drift westward and electrons, eastward.
* form part of the atom's nucleus, around which negative electrons revolve.
* give the nucleus of atoms their charge and are one of the basic building blocks of atoms.
* have a positive charge and determine the chemical element
  - electrons a negative charge
  - that is balanced by the negatively charged electrons
  - charge, neutrons have no charge and electrons have a negative charge
  - electric charge while neutrons have no charge
* have a positive electrical charge and electrons a negative charge
  - while neutrons have none
* have a positive electrical charge, and electrons have a negative charge
  - neutrons have no electrical charge
  - single positive charge
  - antiprotons
  - one down, and neutrons have two
* have positive charges while electrons have negative charges
  - charges, and electrons negative ones
  - the same charge as electrons, only positive
* have two ups and a down
  - ups, and neutrons have one
* includes sections.
* only have two positive attachment points.
* play a major role in respiration and many enzymatic reactions.
* produce an electric field across the photosynthetic membrane.
* quickly become neutralized as they combine with electrons.
* release most of their energy when they stop.
* repel each other in the same way
  - electrons because they have the same charge
* return through the membrane by way of a channel protein.
* typically sell for half the price of import equivalents.
+ Composite particle: Subatomic particles
  * Simple particles like protons are actually composites of multiple quarks. Protons are known as baryons, which means that they are made of exactly three quarks. Baryons are in a family called Hadrons, which simply means that they are made of quarks. The only other subcategory of Hadrons is Mesons, which are made of one quark and one antiquark.
  * Protons are made of quarks. A proton is believed to be made up of 3 quarks, two up quarks and one down quark. A proton has a very small mass. The mass of the proton is about one atomic mass unit. The mass of the neutron is also about one atomic mass unit. The size of a proton is determined by the vibration of the quarks that are in it, and these quarks effectively form a cloud.
+ Large Hadron Collider: Buildings and structures in Switzerland :: Nuclear physics
  * The LHC starts with hydrogen atoms, and ionizes the atoms' electrons so that only protons are left. Protons are parts of atoms with a positive charge. The protons are moved around the Large Hadron Collider at very high speeds by giant supercooled electromagnets. These magnets have to be very cold to work and they are cooled by liquid helium. It then reverses and creates mass.
