Whennuclear fissionor fusion occurs, many types of radiation are created, including alpha particles, beta particles, gamma rays and neutrons. Alpha and beta particles would mostly be harmless. Although they're fast-moving particles, they're too big to pass through much matter -- alpha particles ...
It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the number of protons, you wind up with a different element altogether. If you alter the number of neutrons in an atom, you wind up with an isotope. For...
Normal atoms are made up of protons and neutrons in the nucleus (see How Atoms Work), surrounded by a cloud of electrons. In plasma, the electrons separate from the nucleus. Once the energy of heat releases the electrons from the atom, the electrons begin to move around quickly. The ...
At these energies, each individual proton or neutron in a nucleus acts independently, so the absorption depends on the number of protons or neutrons that each neutrino encounters. The Earth's core is particularly dense, so absorption is largest there. By comparison, the most energetic neutrinos t...

This is because the mass of a substance is dependent on the molecular weight of the substance, which is determined by the number of protons and neutrons in the nucleus of the atom. Therefore the molar mass of a substance such as air is dependent on the sum of all the volume fractions ...
Use wire cutters to make a cut in each of the craft rings. Step 5 Thread beads onto the craft rings to represent electrons. Follow your diagram sketch as to how many electrons to include for each sub-shell, working form smallest to largest. For example, a nitrogen atom will have three ...
Scientists at the Department of Energy's Oak Ridge National Laboratory used neutrons, isotopes and simulations to "see" the atomic structure of a saturated solution and found evidence supporting one of two competing hypotheses about how ions come togethe
When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons). Carbon-14 is radioactive, with a half-life of about 5,700 years. For more information on cosmic rays...
These substances are injected into the body, and are usually tagged with a radioactive atom, such as Carbon-11, Fluorine-18, Oxygen-15, or Nitrogen-13, that has a short decay time. These radioactive atoms are formed by bombarding normal chemicals with neutrons to create short-lived radio...
