WebAtoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 × × 10 −23 g, and an electron has a charge of less than 2 × × 10 −19 C (coulomb). When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass … WebSince it is neutral, it also has eight protons! The periodic table has another number associated with every element, and that is it's atomic mass. For oxygen, the atomic mass is 16 AMU (Atomic Mass Units). In terms of mass, protons and neutrons have about the same mass, and electrons have very little mass in comparison.
