The formula for Iron II Chlorate is Fe(ClO₃)₂. Here's how we arrive at that:

* Iron II: This indicates that the iron ion has a +2 charge (Fe²⁺).

* Chlorate: This refers to the polyatomic ion ClO₃⁻, which has a -1 charge.

To balance the charges, we need two chlorate ions (2 x -1 = -2) to match the +2 charge of the iron ion. This gives us the final formula: Fe(ClO₃)₂.
