Can ionization energy be positive negative

WebAug 21, 2024 · Ionization energy is the minimum energy required to remove the most loosely bound electron from atom of an element in its ground state. According to IUPAC covention about sign of energy, if energy enters the system, its sign is positive and if energy leaves the system, its sign is negative. 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 …

Mulliken recognized that an atom’s tendency to gain or lose electrons could therefore be described quantitatively by the average of the values of its first ionization energy ...

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.
