ViviYes, 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.

What elements have such small masses that they are not even considered when atomic masses are calculated?
Electrons
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.
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.
