A beta particle is an electron: the mass is 5.4857990946(22)×10−4amu.
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
Atomic mass unit
The atomic mass unit is used to express the measure of the atomic mass.
Atomic Mass Unit (amu)
An electron has a negative charge and a mass close to 0 amu (atomic mass unit).
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.
Atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights.
The abbreviation for atomic mass unit is amu, which stands for atomic mass unit. It is a unit of mass used to express atomic and molecular weights.
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
the answer is the atomic mass unit
AMU stands for atomic mass unit. It is a unit of mass used to express atomic and molecular weights. 1 atomic mass unit is defined as one twelfth of the mass of an atom of carbon-12.
