Atomic Mass unit is the number on the bottom of the Chemical. However, the atomic mass is the number on the top of the chemical minus the number on the bottom. b.t.w The no. of neutrons = top no. minus bottom no.
The atomic mass unit is used to express the measure of the atomic mass.
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
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.
"18 atomic units" is a (semi) sensible mass (it ought to be "18 atomic MASS units", but that's a minor quibble). "18 atomic gram" is just nonsense. That's the biggest difference.
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
Atomic mass unit
Atomic Mass Unit (amu)
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.
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
the answer is the atomic mass unit
