Answer

Explanation:

Step1: Identify elements in formula

The formula FeS₂ has iron (Fe) and sulfur (S) elements.

Step2: Match with models

The pyrite model has blue (Fe) and yellow (S) atoms which match Fe and S in the formula. The boron - nitride model has B and N, and the gallium - arsenide model has Ga and As which do not match FeS₂.

Answer:

pyrite
