negatively and positively
charged ions, repulsion between
atoms with the same
charge may drive the structure to become unstable under pressure.
Gases (such as air, which has an equal number of positive and negative
charges) become plasma when energy (such as heat or electricity) causes some of the gas's
atoms to lose their
negatively charged electrons, creating
atoms with a positive
charge, or positive ions, surrounded by the newly detached electrons.

The hydrogen
atom consists of a single
negatively charged electron bound to a single positively

In the end, the strong separation of
negatively charged electrons and now positively
charged atoms, or ions, creates the forces that accelerate an ion beam toward the tumor.

charged particles to repel one another in the same way it allows positively
charged protons to bind to one another within the nuclei of ordinary
atoms.
