Answer
A. Giant IonicAfter analyzing the compound, we know iron(III) bromide, formed by electrostatic attractions between iron(III) ions and bromide ions is a giant ionic structure or lattice. Repeating patterns of ions and charge neutrality characterizes such structures. Reasonably they are commonly found in many groups one and two compounds, but they can arise in transition metals when forming bonds with reactive non-metals similar to iron(III) bromide.
Explanation
## Step 1: Analyze CompoundWe first need to look at the nature of the compound that is forming. The compound provided in the question is 'iron(III) bromide.' This is a compound where we are looking at a transition metal (iron) being bonded with non-metals (bromine atoms). Hence, this represents a type of ionic bonding.## Step 2: Identify StructureIonic bonds form when one atom gives up electrons to another atom, resulting in generating both positive and negative ions. This formation allows the formation of giant ionic lattices structure where strong electrostatic forces hold the ions resulting in a giant ionic structure due to the repeating pattern of ions.
