Some isotopes are stable and some are
WebWhat are Stable Isotopes? The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of … Web1, 3, & 6. Each isotope has a half-life that is different from the half-life of other isotopes. The half-life of an isotope changes constantly. An isotope's half-life is not affected by temperature, pressure, density, or concentration. Use the drop-down menus to complete each sentence. The number of half-lives changes.

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.
