The average Atomic Mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the Periodic Table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.

The of an element is defined as the average mass of an atom of the element compared to 112th the mass of an atom of carbon-12. What are the three missing words?
relative atomic mass
What is the approximate atomic mass of a neutron?
The approximate atomic mass of a neutron is 1 unified atomic mass unit, which is equivalent to 1.008665 atomic mass units when considering the mass excess.
Why Cu has a relative atomic mass?
Copper (Cu) has a relative atomic mass because it is an average value that considers the different isotopes of copper and their abundance in nature. The relative atomic mass provides a more accurate representation of the average mass of an atom of copper compared to using just the mass number of the most abundant isotope.
Is the meaning of relative atomic mass is the same as atomic weight?
Yes, the relative atomic mass and atomic weight are used interchangeably to represent the average mass of an element's atoms compared to the mass of a carbon-12 atom. This value is unitless and is typically represented in atomic mass units (amu).
What is the difference between average atomic mass and atomic mass?
Average atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundances. Atomic mass refers to the mass of a single atom of a specific isotope of an element.
What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
What is the average attomic mass for titanium?
The average atomic mass of titanium is approximately 47.87 amu (atomic mass units).

What tells you how heavy an element's atoms are compared with atoms of other elements?
The atomic mass of an element tells you how heavy its atoms are compared with atoms of other elements. Atomic mass is the average mass of an atom of an element, taking into account all its isotopes and their abundance.
What is the approximate atomic mass of a neutron?
The approximate atomic mass of a neutron is 1 unified atomic mass unit, which is equivalent to 1.008665 atomic mass units when considering the mass excess.
Why Cu has a relative atomic mass?
Copper (Cu) has a relative atomic mass because it is an average value that considers the different isotopes of copper and their abundance in nature. The relative atomic mass provides a more accurate representation of the average mass of an atom of copper compared to using just the mass number of the most abundant isotope.
What is the average atomic mass of lithuim?
The average atomic mass of Lithium (Li) is 6.941.
Is the meaning of relative atomic mass is the same as atomic weight?
Yes, the relative atomic mass and atomic weight are used interchangeably to represent the average mass of an element's atoms compared to the mass of a carbon-12 atom. This value is unitless and is typically represented in atomic mass units (amu).
What is the difference between average atomic mass and atomic mass?
Average atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundances. Atomic mass refers to the mass of a single atom of a specific isotope of an element.
The atomic mass of an atom is based on a comparison with the mass of sulfur-32?
No, the atomic mass of an atom is based on the average mass of an element's isotopes weighted by their relative abundances. The atomic mass unit (amu) is equal to one-twelfth of the mass of a carbon-12 atom, not sulfur-32.
What is the difference between atomic mass and average atomic mass?
Atomic mass refers to the mass of an individual atom of a specific element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature. Average atomic mass is usually listed on the periodic table, while atomic mass is specific to a single isotope.
What element has an average atomic mass of about 12?
Carbon has an average atomic mass of about 12.
