The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...

What is the difference between an atom and an ion? Atoms, Elements, and Matter The base unit of matter is the atom, where matter is made up of different types of atoms, i.e. elements. Each atom of a specific element contains some number of neutrons (neutrally-charged), protons (positi...
AMU stands for atomic mass unit and is a standard unit of mass that quantifies mass on an atomic or molecular scale. It is defined as one-twelfth the mass of a carbon-12 atom. Grams, on the other hand, are a metric unit of mass, equal to one-thousandth of a kilogram. While AMUs...
The majority of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom's constituent particles, with a mass of 9.11 x 10-31kg and a size too small to be measured by current techniques. Protons have a mass that is 1,83...
