Combining ions to make ionic compounds

  1. 1. The problem statement, all variables and given/known data

    How do i combine 2 different ions to make an ionic compound


    2. Relevant equations

    Na+¹ + O-² --->


    3. The attempt at a solution

    I have no idea what to do plus im new to this forum. Please try to help me in the simplest way possible because my teacher has failed twice to explain it to me. If their is a formula or something, please tell me it.

    Does one mean stoichiometrically, or structurally as in a crystal lattice.

    In the example, Na prefers +1 valence state, while O prefers -2, so the compound in that case would be Na2O. For ionic compounds the positively charge cation is usually electropositive, and tends to give up electrons readily to the negatively charged anion, which is electronegative, i.e. has an affinity for electrons.

    Also, see discussions about ionic compounds.

    One has to understand the difference between ionic and covalent bonds

  4. How did you figure out Na2O from Na+¹ + O-²?
