* Ionic Compounds: These are formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

* Sodium (Na): Sodium is a metal and tends to lose one electron to form a +1 cation (Na⁺).

* Chlorate (ClO₃): The chlorate ion is a polyatomic anion with a -1 charge. It consists of a chlorine atom bonded to three oxygen atoms.

Therefore, sodium chlorate is formed by the ionic bond between the sodium cation (Na⁺) and the chlorate anion (ClO₃⁻).
