Comparing Chemical Formulas of Galena and Iron Pyrite

Comparison of Galena and Iron Pyrite

Galena and iron pyrite are both naturally occurring minerals with distinct chemical compositions. One key similarity between the two minerals is the presence of sulfur in their chemical formulas. Sulfur is denoted by the symbol S in both PbS (galena) and FeS2 (iron pyrite).

However, there is a significant difference between the chemical formulas of galena and iron pyrite. Galena contains lead (Pb) in its composition, represented by the atomic symbol Pb, while iron pyrite contains iron (Fe), represented by the atomic symbol Fe. This distinction in elemental composition gives each mineral its unique properties and characteristics.
