atomimassaan
Atomimassaan is a Finnish term that translates to "atomic mass" in English. It refers to the mass of an atom, which is primarily determined by the number of protons and neutrons in its nucleus. The mass of electrons also contributes to the atomic mass, but their contribution is significantly smaller due to their much lower mass compared to protons and neutrons. Atomic mass is typically measured in atomic mass units (amu), where one amu is defined as one-twelfth the mass of an unbound neutral atom of carbon-12. This unit provides a convenient way to express the masses of individual atoms and molecules.
The concept of atomic mass is fundamental in chemistry and physics. It is used to calculate molar
