Expert Answer 100% (1 rating) An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is View the full answer Previous question Next question Atoms have the same number of protons and electrons, making them neutral. b. A few points detailing the discovery and the properties of electrons are listed below. Note that when particles are added to your model you can see if the atom is stable or unstable (labeled in the center), and if it is neutral or an ion (labeled on the outer rings). When an atom gains electrons, this results in a negative charge. The most common charged particles are the electron and proton. Protons are positive, neutron are neutral (having no charge) and electrons are negative. Everything in the world, whether natural or synthetic, is made up of tiny structures called atoms, which are made of protons, neutrons, and electrons. But there are cases in which an atom can acquire an electrical charge. of electron in the ion = x. There are three subatomic particles that combine to make atoms: protons, neutrons, and electrons. Atoms and ions both have a nucleus. Ionizing particles lose energy in matter through either nuclear or electronic energy loss Because electrons are easy to shed, electronic energy loss is more common Only at the end of their "range" do ionizing particles have nuclear energy loss Total energy loss can be estimated as electronic energy loss Called "linear energy transfer" (LET), which are usually in the units of MeV -cm2/mg When an atom loses electrons, it forms a positive ion called a cation. When atoms gain or lose electrons they become more stable. Note . When an electron is lost, the balance shifts with an extra proton, giving the atom a positive charge.
