WebIonization is the term given to the process by which electrons are removed from their orbit around a particular atom, causing that atom to become charged, or ionized. This process can occur when radiation of sufficient strength interacts with normal atoms. Radiation that is not powerful enough to trigger this process is known as non-ionizing.

Web6 mei 2024 · 506. 14. Ions are atoms/molecules where the total number of electrons does not equal the total number of protons. If you have more electrons than protons, one has an anion - a negatively charged ion. If you have more protons than electrons, one has a cation - a positively charged ion. And then you can also have zwitterions. Webwhere A-is the ionized drug and HA the unionized drug. For a weak base: pH = pKa + log(B/HB +), where B is the unionized drug and HB + is the ionized drug. Thus, when the local pH is equal to the pKa of the drug, the drug will be 50% ionized and 50% unionized (log 1 = 0). There is further information on this area in the suggested reading.
