The principal factor is the neutron to proton ratio. At close distances, a strong nuclear force exists between nucleons. This attractive force comes from the neutrons. More protons in the nucleus need more neutrons to bind the nucleus together.

WebSome of these isotopes are stable while others are unstable or radioactive. Radioactive isotopes emit nuclear radiation in the form of rapidly moving particles or high energy electromagnetic waves. The particles are emitted from the nucleus itself and their removal results in changing the atom from one isotope to another. WebPart 1 – Create a “Band of Stability” You will be graphing the proton and neutron numbers for some isotopes that are known to be stable. 1.

WebA significant difference in the mean 13 C of kimberlites from different localities is indicated. For those kimberlite locations where he differences between their mean δ 13 C and δ 18 0 values are too great to be explained by a "combined isotopic effect process", then an inhomogeneous source reservoir of carbon isotopes is inferred. 展开 WebAn isotope is an alternative form of an element. Each isotope of an element has the same number of protons, but a different number of neutrons. The isotope is represented by the atomic symbol and mass number, such as He-4. Some isotopes are stable, while others are radioactive, which means the atoms decay over time and emit radiation.
