Question

How potive or nagtive anion or formed

Answer 1

Answer:

Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged. ... The metals form positively-charged ions and the non-metals form negatively-charged ions.

Answer 2

Answer:

• By adding an electron to an atom or a molecule, some energy states below the vacuum level can become populated, i.e. negative ions. The basic principle of negative ion formation is to attach an extra electron to a neutral atom by an exothermic reaction. ...

• Positive ions are formed by atoms or molecules suffering an inelastic collision with an energetic electron in which an electron is lost from the atom or molecule (electron impact ionization). The degree of ionization of the plasma depends strongly on the electron density and energy distribution in the gas.
