We’re being asked to classify each given substance as an atomic element, molecular element, molecular compound, or ionic compound. 

Let’s first differentiate an atomic elementmolecular elementmolecular compound, and ionic compound.


Atomic Element

▪ exists anytime an element is by itself

Molecular Element

▪ exists anytime the same type of element (nonmetals) are combined together (Example: S8)
▪ Recall the diatomic moleculesH2, N2, F2, O2, I2, Cl2and Br2
