  • rest mass of an atom in its ground state
aatomimass preferred
Usage examples
  • Aatomimassi väljendatakse sageli SI-välises ühikus dalton (tähis: Da või u), kus 1 dalton on määratletud kui 1⁄12 ühe süsinik-12 aatomi massist, puhkeolekus.
Good to know
  • Aatomimasside otsene võrdlemine ja mõõtmine toimub aatomispektroskoopia massispektri abil.

Good to know
  • Vananenud termin, kasutati olukorras, mil termini "mass" asemel kasutati terminit "kaal".
atomic mass preferred
Usage examples
  • Atomic mass is often expressed in the non-SI unit dalton (symbol: Da, or u), where 1 dalton is defined as 1⁄12 of the mass of a single carbon-12 atom, at rest.
Good to know
  • Direct comparison and measurement of the masses of atoms is achieved with mass spectrometry.
