WebMar 30, 2024 · Brad Cole. Ionization is when an atom or molecule gains either a positive or negative charge. It can occur in one of two ways: first, when electrons are either gained or lost by a particle; second, when one atom or molecule combines with another atom or molecule that already has a charge. The charged particle itself is called an ion. WebMay 22, 2013 · This can be negative because some atoms (halogens) like to have an extra electron added, so energy is released. And it's positive for atoms that don't want that … WebAnswer: In chemistry, a negative assigned to an energy value indicates that the process involved is exothermic, meaning the system releases this quantity of energy to the surrounding (ie; the system loses (-) this quantity of energy).
