The Atomic Mass of an element is determined by calculating the weighted average of the masses of its isotopes, taking into account their relative abundance.

How can one determine the atomic weight of an element?
The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.
How do you calculate the atomic weight of an element?
The atomic weight of an element is calculated by taking the weighted average of the masses of its isotopes, based on their abundance in nature. This is done by multiplying the mass of each isotope by its abundance, adding these values together, and then dividing by 100.
What identifies and element?
Atoms are differentiated by their number of protons. This is equal to the atomic number of the element. Additionally, in chemical formulas, each element is represented by a unique atomic symbol.
On what were the original atomic weights based?
The original atomic weights were based on the mass of hydrogen.
What do the initials A.M.U. stand for?
Atomic Mass Unit
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
The atomic mass is determined by?
atomic mass is determined by adding the number of protons and neutrons.this can be seen in the periodic table as the average atomic mass below the name of the element
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
What two pieces of information can be determined from the atomic mass?
The number of protons and neutrons in the atom can be determined from the atomic mass. The atomic mass represents the average mass of the isotopes of that element in atomic mass units.
Does the element change when the atomic mass changes?
No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.
How is the mass of 1 mole of an element determined?
The mass of 1 mole of an element is determined by summing the atomic masses of each atom in the element's chemical formula. This value is typically expressed in grams per mole, referred to as the molar mass. It is based on the relative atomic masses of the isotopes that make up the element.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
What two factors determines the atomic mass of a element?
The atomic mass of an element is determined by the number of protons and neutrons in its nucleus. Protons and neutrons have almost the same mass and contribute to the overall mass of the atom. Electrons, on the other hand, have negligible mass compared to protons and neutrons and do not significantly affect the atomic mass.
How is the average atomic mass of an element determined?
The average atomic mass of an element is determined by taking into account the mass and relative abundance of each isotope of the element. This is calculated by multiplying the mass of each isotope by its relative abundance and summing these values together. The resulting value is the average atomic mass of the element.
Is the element with largest atomic mass always present in highest percentage by mass in a compound?
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.
