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.
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.
When the ionic compound Kl is dissolved what attraction pulls l ions into solution?
When I- ions are merged with iodine molecules, a complex of I3- is formed which is stable in an aqueous medium.
Why is dilute h2so4 most suitable as compared to hcl and hno3 in kmno4 titrarion?
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.
Why cationic molecular ions are greater then anionic one?
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.
Why are ions not stable?
Ions are stable.
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.
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)
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.
What negative ions have a high electron affinity?
None, it has a stable structure
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.
Is the beryllium ion stable?
Nether. (It should make a cation, but it's too small.)
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
What is the charge on stable ion of neon?
Neon does not form any compounds or ions.
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
Why are cuprous ions less stable than cupric ions?
due to its oxidation states or simply the explanation is in the ground and excited states of an atom
