Chemistry For Dummies. Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of half-lives is radioactive dating. This has to do with figuring out the age of ancient things. If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn ...Water has many unusual properties because of its polar covalent bonds. Oxygen has a larger electronegativity than hydrogen, so the electron pairs are pulled in closer to the oxygen atom, giving it a partial negative charge. Subsequently, both of the hydrogen atoms take on a partial positive charge.May 3, 2023 · Calculating pH when given the pOH. Calculating pH when you know the pOH (or vice versa) is probably the easiest of the acid-base calculations. Here’s the formula: pH + pOH = 14. Simply subtract the given value from 14 (keeping significant digits in mind) to get the value that you need. Chemistry For Dummies. Nuclear fission occurs when a larger isotope breaks apart into two or more elements. Scientists usually accomplish this task (for some controlled nuclear reactions) by bombarding a large isotope with a second, smaller one — commonly a neutron. The collision results in nuclear fission.Chemistry For Dummies, 2nd Edition (9781119293460) was previously published as Chemistry For Dummies, 2nd Edition (9781118007303).
