Atomic mass used in a sentence?
The atomic mass of an element is the weighted average of the masses of all the stable isotopes of the element (if it has any), weighted by the natural occurrence levels of the isotopes in the elements as found on earth or in the atmosphere.
What does 12 b m s mean?
It means 12 Bohr Magnetons, a unit for dipole moment used in atomic chemistry.
What is the atomic mass?
See the Web Links for "Answers.com: Atomic mass" to the bottom for the answer. Atomic mass refers to the weight of an atom when compared to aribitary figure that is relative to other atoms.The unit used is 1/12 the weight of a carbon atom (the most prolific around). Atomic mass is used to avoid using very small numbers that would otherwise result if you try to physically weigh an atom.Note that atomic mass is not the same thing as atomic weight. See the Related Question to the left for more information.
What unit are nucleus measured in?
Atomic mass unit; protons and neutrons both weigh about 1 amu1 amu equals approximately [1 gram / (6.023 * 1023)] = 1.66 * 10-24 gramsThe angstrom (symbol Å) is often used to measure distances at the atomic scale.1 angstrom = 10-10 meter, or 0.1 nanometer
What units do you use to mass?
The international unit for mass is the kilogram. 1000 kilograms = 1 ton (metric ton, to avoid confusions); 1/1000 of a kilogram is a gram. Smaller units include the microgram and the nanogram. Non-standard units include the pound, the atomic mass unit, and the electron-volt (an energy unit; this really means electron-volt / c2). In astronomy, multiples of the mass of our Earth or our Sun are also used, especially for comparisons. For example, the black hole at the center of our galaxy is said to have 4 million solar masses - i.e., 4 million times the mass of our Sun.
Si units used for the masses of atomic particles?
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
Relative atomic masses are measured in?
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.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
What is an amu and does it relate to atoms?
An atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. It is defined as a twelfth of the mass of an atom of carbon-12. Since atoms have very small masses, the amu is used to provide a more practical and meaningful scale for representing these minuscule values.
Why interval notation cannot be used to represent the set of atomic masses given?
Why interval, notation cannot be used to represent instead of atomic masses
The mass of an atomic nucleon is nearly?
The mass of an atomic nucleon is approximately 1 atomic mass unit (u) or 1.66 x 10^-27 kg. This value is commonly used as a reference unit for expressing the masses of atomic particles such as protons and neutrons.
What is the definition of units of mass?
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.
Explain Why is atomic mass unit used to express atomic mass?
Originally these relative masses were based on hydrogen, known to be the lightest element, having a mass of 1 u, and all the MORE
The protons has a mass of approx 1 you?
The mass of a proton is approximately 1 atomic mass unit (u) or 1.67 x 10^-27 kg. This mass is used as a reference for atomic and subatomic particle masses.
Define atomic mass unit?
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.
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
