Elements which are "metals" - meaning that they have excess electrons that can flow from atom to atom, and elements that are halogens, meaning that they lack only one electron to have a full electron shell, are both more stable as ions than as neutral elements.
Sodium, for example, has one "extra" electron which is weakly bound; chlorine is a halogen which has space for one extra electron. Sodium Chloride will bind very well as "common table salt".
Chemistry joke: Two Lithium atoms are walking down the sidewalk, and one trips and falls. The other atom asks, "Are you OK?"
The atom that had fallen said "No, I've lost an electron!"
The other atom asked "Are you sure?"
"Yes!" said that fallen atom. "I'm Positive!".

What is produced at the positive electrode for the electrolysis of copper sulfate?
Oxygen will because the sulfate ions are stable so they will stay in the solution.
Why does argon not form ions?
Atoms 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.
Is the valency equal to ionic charge of an atom?
Yes, it is. Since valency is the no. of electrons an element should gain or loose or share to become stable. So, this is true in case of substances which form ions. But elements like carbon never form ions. Its valency is four. It shares electrons to get stable.
Why is ortho phosphoric acid used in titration?
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.
Why ions are stable?
because they form in compund where one atom loses electrons and other gains.
Why are ions not stable?
Ions are stable.
Why can ammonia molecule react with hydrogen ions but not hydrogen gas?
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
What is produced at the positive electrode for the electrolysis of copper sulfate?
Oxygen will because the sulfate ions are stable so they will stay in the solution.
What is the relationship between the stable ions and the noble gases?
Generally (but not always) stable ions will have the same the electronic configuration as that of noble gases (completely filled valence shells / orbitals)
What ions are found in rust?
As rust is iron that is returning to a more stable state then most of the ions is iron
What is the symbols of the ions with 19 protons and 18 electrons?
Ar0 there is no ions formed because it is already stable.
Why Na and Cl are poisonous but Na Cl is not?
Because the ions in sodium chloride have full outer shells, so they're stable.

What negative ions have a high electron affinity?
None, it has a stable structure
Is the beryllium ion stable?
Nether. (It should make a cation, but it's too small.)
Why is ortho phosphoric acid used in titration?
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.
