Here is the equation for the alpha decay of radon-219 ... Carbon-14 is a radioactive isotope of carbon. Each atom has six protons and eight neutrons. It decays to form nitrogen, which has seven ...

However as the number of protons increases, more neutrons are needed to keep the nucleus stable. For example lead, lead-206 has 82 protons and has 124 neutrons.

The technique of neutron activation analysis is based on the measurement of radiation released by the decay of radioactive nuclei formed by neutron irradiation of the material. The most suitable ...

The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation ...

Electron antineutrinos are emitted during nuclear beta decay, a type of radioactive decay in which a neutron decays into a ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

in radioactive beta decay. In the most common form of this decay, beta-minus decay, a neutron decays into a proton, also spitting out a negatively charged electron in order to conserve electric ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...

Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great, radioactive decay will occur. Up to two electrons may exist in the atom's first shell.

He called it a neutron, and imagined it as a paired proton ... They used a different method for tracking particle radiation. Chadwick repeated their experiments but with the goal of looking ...
