Atomic Mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.
Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.
Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
The atomic number of lead is 82. The number of neutrons in an isotope is always the difference between the isotopic mass number and the atomic number. In this instance, 206 - 82 = 124.
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
The relationship between atomic mass and relative abundance of isotopes was the mas number is the number of protons and neutrons in a normal atom of the element and tha atomic mass is the actual mass of the atom, measured in grams.
When atomic mass is expressed in unified atomic mass units, it is similar to isotopic mass and has the same numerical value as that of atomic mass. The atomic mass or the relative isotopic mass is the mass of one atom which at a time can be only one isotope.
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
The atomic number of lead is 82. The number of neutrons in an isotope is always the difference between the isotopic mass number and the atomic number. In this instance, 206 - 82 = 124.
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
The relationship between atomic mass and relative abundance of isotopes was the mas number is the number of protons and neutrons in a normal atom of the element and tha atomic mass is the actual mass of the atom, measured in grams.

Atomic number is the number of a chemical element in the periodic table of Mendeleev; it is equal in the neutral state with the number of protons or electrons. Atomic weight is the mass of a chemical element (considering the isotopic composition) expressed in atomic mass units.
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.
