The energy required to remove an electron from an atom or ion. It's like the strength of the bond holding together our metaphorical magnet pieces - it determines how much energy you'd need to pull them apart.
A substance that produces free ions when dissolved in water and thus conducts electricity. In our analogy, this would be similar to a magnet that not only sticks together but can also conduct electricity.
The force of attraction between oppositely charged ions in a compound. This is the "magnetic force" that holds our cations and anions together in an ionic compound.
