Final answer:
Hydrogen is the element with atoms having the smallest mass.
Step-by-step explanation:
In Chemistry, the element with atoms that have the smallest mass is Hydrogen. Hydrogen is the lightest element in the periodic table, with an atomic mass of approximately 1 gram per mole.
For comparison, the atomic mass of other elements is much larger. For example, the atomic mass of Oxygen is 16 grams per mole, and the atomic mass of Carbon is 12 grams per mole. Therefore, compared to other elements, Hydrogen has the smallest mass for its atoms.
