Which of the following is a stable ion or are stable ions?
Na +1
Ca +2

  • chemistry -

    Your question doesn't make sense to me. Z is not an ion. And Na+1 and Ca+2 exist but ONLY in compounds such as NaCl or CaO. Both Na+1 and Ca+2 are very reactive; therefore, you usually see them only combined with a negative ion.

    sorry i meant zn -2

    No such thing as Zn-2. There is a Zn+2
