Yes, atomic masses are typically measured in Atomic Mass units (amu), which are defined as one twelfth of the mass of an atom of carbon-12. This unit is convenient for expressing the masses of atoms because it allows for a more manageable scale of values compared to using the actual mass in kilograms or grams.

How many atomic mass units does an electron have?
An electron has a mass of about 0.00054858 atomic mass units (amu) or approximately 1/1836 of a proton or neutron.
The atomic mass listed in the periodic table is the?
The atomic mass listed in the periodic table is the weighted average of the masses of all the isotopes of an element, taking into account their abundance in nature. It is measured in atomic mass units (amu) and provides an average value that reflects the isotopic distribution of the element.
What elements have such small masses that they are not even considered when atomic masses are calculated?
Electrons
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Most atomic masses on the periodic table are decimal numbers because they are weighted averages of the masses of all isotopes of an element, taking into account their relative abundance. Since isotopes have different masses, the atomic mass is typically not a whole number.
What nuclide is used as the standard in the relative scale for atomic masses and What is it's assigned atomic mass?
Carbon-12 (12C) is used as the standard in the relative scale for atomic masses, and its assigned atomic mass is 12 atomic mass units.
True or false relative atomic masses sre measured in amus?
true
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).
What is vanadium's atomic radii?
vanadiums atomic weight is 50 AMUs
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.
A Russian chemist named Dmitri Mendeleev organized elements by?
Mostly by atomic mass, but in some cases by (educated) guess where he thought the measured atomic masses weren't correct.
Why are gram formula masses called relative masses?
They are called relative masses because all of the masses of the elements are measured relative to the mass of an isotope of carbon called carbon-12. Carbon-12 has been assigned a mass of exactly 12 atomic mass units. One atomic mass unit has an actual value of 1.660538782(83)×10^−27 kg.
By adding the atomic masses?
You will get the atomic bomb!
Is chlorine measured in grams?
Chlorine is typically measured in mass units, such as grams, when quantifying the amount of chlorine in a sample or substance. This is because chlorine, like other elements, has a specific atomic mass that can be represented in grams.
What element is 40 amu?
The element with an approximate atomic mass of 40 amu is Calcium (Ca).
Mass is measured by this unit?
The SI unit for mass is the kilogram.Other units include pounds, tonnes, metric tonnes, atomic mass units, eV/c2, Earth masses, Solar masses. The latter two are often used for comparisons in astronomy.
The current standard for atomic masses is?
The current standard for atomic masses is based on the Carbon-12 isotope. It is defined as exactly 12 atomic mass units (amu), with all other atomic masses determined relative to it. This standard allows for consistency in measurements and comparisons of atomic masses across different elements.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
