because they form in compund where one atom loses electrons and other gains.

∙ 11y agoAtoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable. Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.
Phosphoric acid is used in titraions involving Iron(III) ion. Ferric ions are not stable in aqueous medium. It forms a stable complex with phosphate ions.
When I- ions are merged with iodine molecules, a complex of I3- is formed which is stable in an aqueous medium.
In water SO4 ions are stable and do not interfere in reaction while Cl ions and NO3 ions are unstable and oxidizing agents and may disturbed the redox reactions.
It is wrong. Cations are smaller than ions. It is because when cations are formed the outer shell of the element is removed but this does not happen with anions.
Ions are stable.
As rust is iron that is returning to a more stable state then most of the ions is iron
Ar0 there is no ions formed because it is already stable.
Generally (but not always) stable ions will have the same the electronic configuration as that of noble gases (completely filled valence shells / orbitals)

None, it has a stable structure

Nether. (It should make a cation, but it's too small.)
The most stable atoms/ions have 8 electrons in their outermost shell.
Neon does not form any compounds or ions.
hydrogen gases are stable so they will react no further while hydrogen ions have no electrons so it will react with the ammonia molecule thus becoming g stable
due to its oxidation states or simply the explanation is in the ground and excited states of an atom
