Define atomic mass unit

Answer 1

An Atomic Mass unit, also known as AMU, is the unit used to measure the weight of protons and neutrons. If an element has an atomic mass of 84 AMU, that element has a total of 84 protons and neutrons in its nucleus.

Answer 2

An atomic mass unit is a unit that's used to measure the masses of atoms and molecules. Today, we use the unified atomic mass unit (u) which is 1/12 the mass of a carbon-12 nucleate that is unbound, at rest, and in it's ground state.

Answer 3

Atomic mass unit (amu) is a unit of mass used to express the mass of atoms and subatomic particles. One atomic mass unit is approximately equal to the mass of a proton or neutron. It is defined as 1/12 the mass of a carbon-12 atom.

Answer 4

A unit of mass equal to 1/12 the mass of the most abundant isotope of carbon, carbon 12, which is assigned a mass of 12.

Answer 5

Also called dalton. a unit of mass, equal to 1/12 the mass of the carbon-12 atom and used to express the mass of atomic and subatomic particles.

Answer 6

Definition: an atomic mass unit or amu is one twelfth of the mass of an unbound atom of carbon-12. It is a unit of mass used to express atomic masses and molecular masses.

Answer 7

The approximate mass of one Hydrogen atom, proton or neutron.

1/12 the mass of a single atom of Carbon-12, in its ground state.
