What is the average atomic mass for neptunium?
The most important isotope of neptunium (237Np) has the atomic mass 237,048 173 4(20).
What element has the volume of 43 ml and the mass of 305.859?
There is no element with that atomic mass, the element that comes the closest is Ununbium with an atomic mass of 277.0.
The naturally occurring isotopes of sulfur have masses of 32 33 34 and 36 amu. The atomic mass of sulfur is 32.06 amu. Which of these isotopes is the most abundant?
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
Why do elements have a listed average atomic mass and not just atomic mass?
Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
What is the average atomic mass of iron?
Iron is a meta element. Atomic mass of it is 56.
Why is the atomic mass of an element an average?
The atomic mass is an average because most elements consist of a mixture of isotopes.

How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.

Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
What is the atomic mass in Hindi?
The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units.[1] The atomic mass is the total mass of protons, neutrons and electrons in a single atom.[2]The atomic mass is sometimes incorrectly used as a synonym of relative atomic mass, average atomic mass and atomic weight; these differ subtly from the atomic mass. The atomic mass is defined as the mass of an atom, which can only be one isotope at a time and is not an abundance-weighted average as in the case of atomic weight. In the case of many elements that have one dominant isotope the actual numerical similarity/difference between the atomic mass of the most common isotope and the relative atomic mass or standard atomic weights can be very small such that it does not affect most bulk calculations-but such an error can be critical when considering individual atoms. For elements with more than one common isotope the difference even to the most common atomic mass can be half a mass unit or more (e.g. chlorine). The atomic mass of an uncommon isotope can differ from the relative atomic mass or standard atomic weight by several mass units.
How is the atomic mass of each element on the periodic table calculate?
The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value.

Three isotopes of element X occur in nature X-16 X-17 and X-18 If the atomic mass of X is 17.9994 which of the three isotopesthe most abundant?
The most abundant isotope of element X is X-17 because its atomic mass is closest to the average atomic mass of 17.9994. This means that X-17 is more abundant than X-16 and X-18 in nature.
Why is the average atomic mass of most elements the same in every sample that has been analyzed?
The average atomic mass of elements remains consistent across samples because it is calculated based on the weighted average of an element's naturally occurring isotopes and their abundances. Since isotopic ratios are generally uniform in nature, the average atomic mass does not vary significantly from one sample to another. Additionally, atomic mass is defined relative to the standard atomic mass unit, allowing for a reliable comparison across different samples. Thus, regardless of where or how a sample is taken, the average atomic mass remains the same.
