ANY element CAN form an ion, but the noble gases, the right-most column of the Periodic Table do not under normal circumstances.
Barium is +2 valenced ion, so its oxidation state is +2 in ion form (Ba2+) and 0 in elemental (Ba) form
Chloride is an ion that can form ionic bonds. Elemental chlorine is covalently bonded.
No, the chloride ion is a single elemental ion, Cl-.
No. Fluorine is a chemical element. It will readily form fluoride ions.
No, nitrogen typically carries a charge of -3 only in specific compounds or complex ions, such as in the nitride ion (N3-). In most common compounds and biomolecules, nitrogen carries a charge of -3 only in specific circumstances and not as a general rule.
which element can only formed one ion
Actinium form the ion Ac(3+) and only in AcH2 is divalent.
yes
The only probable ion to form from Lithium is the Li+ ion.
No, carbon does not typically form cations under normal conditions because it is more stable in its elemental form or as an anion due to its electronegativity. Cations are formed by losing electrons, which is not a common behavior for carbon.
No, elemental Bromine or Br2 is not an ion
The chloride ion is neither acidic nor basic. Elemental chlorine itself is not acidic, but it will react with water to form hydrochloric acid and hypochlorous acid.
