WebOnly 90 isotopes are expected to be perfectly stable, and an additional 161 are energetically unstable, [citation needed] but have never been observed to decay. Thus, 251 isotopes ( nuclides) are stable by definition … WebAtoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 × × 10 −23 g, and an electron has a charge of less than 2 × × 10 −19 C (coulomb). When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit …
