Web15 de ago. de 2024 · Stage 1: Ionization: The atom is ionised by knocking one or more electrons off to give a positive ion. This is true even for things which you would normally expect to form negative ions (chlorine, for example) or never form ions at all (argon, for example). Mass spectrometers always work with positive ions. Webionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons. Ionization is one of the principal ways that radiation, such as charged particles and X rays, transfers its energy to matter. In chemistry, ionization often occurs … sickness like cancer
