Front

What is the difference between a diatomic element and a compound?

Back

A diatomic element consists of two atoms of the same element (e.g., O2), while a compound consists of two or more different elements (e.g., H2O).

Front

What is the significance of subscripts in chemical formulas?

Back

Subscripts indicate the number of atoms of each element in a compound (e.g., in H2O, the '2' indicates there are two hydrogen atoms).

Front

What is a molecular formula?

Back

A molecular formula shows the actual number of atoms of each element in a molecule (e.g., C2H4 for ethylene).
