What is the kind of bond that forms a salt?

Answer 1

This is an electrostatic bond between cation and anion; in other words an ionic bond.

#Na^+ + Cl^(-) rarr Na^+Cl^(-)(s)#

You have discrete charged particles, i.e. ions, with opposite electric charges. These are electrostratically attracted, and form a strong, non-molecular bond, which operates over the entire ionic lattice. And thus cation and anion, in appropriate quantities, form a #"salt"#.

High (nearly infeasible) melting and boiling points, as well as extremely low solubility in non-polar solvents, are indicative of the strength of this interaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
