ZnS, zinc sulfide (or zinc blende) forms an FCC unit cell with sulfide ions at the lattice points and much smaller zinc ions occupying half of the tetrahedral holes in the structure. What are synonyms for empirical formula? An ionic or a giant covalent compound is described by a simple formula commonly called as the empirical formula. Empirical formula is defined as "the formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms." Your textbook uses an abbreviated form of this, known as the 95% Rule, because 95% is the most commonly used interval. Compounds are combinations in fixed proportions of the chemical elements.
