Ionization occurs when
the proton in the nucleus exchanges an electron with the neutron, which creates energy.
electrons are bundled together to create more energy.
an electrically neutral atom loses an electron and becomes a positively charged ion and the fre electron a negative ion.
a positive electron exchanges its positiveness for a proton.
an electrically neutral atom loses an electron and becomes a positively charged ion and the fre electron a negative ion.
Rationale: an electrically neutral atom loses an electron and becomes a positively charged ion and the free electron a negative ion, at which time it can interact with live tissue.
