6 (a) An element X has an atomic number of 24 and a relative atomic mass of52.06. The natural element consists of four isotopes. The mass spectrum of the element X produced the following peaks of three of the isotopes on the chart recorder.Percentage83.804.302.4050 51 52 53 54 55 56 ...
Here they do not want decimals, so we round this answer, giving us 157 amu as the average atomic mass of element R. Note: An average atomic mass will be a value closest to the isotope with the largest abundance. Since that was isotope 3 with an abundance of 0.7988 or 79.88%, we se...
What does 'elements made up of atoms with the same number of protons' mean? What is an Atomic Mass Unit (AMU)? The common isotopes of carbon are 12C and 13C. The average mass of carbon is 12.01115 amu. What is the abundance of the 13C is...

1 The relative atomic mass of an element is always D A the mass of an atom of the element relative to i2 the mass of a carbon-12 atom. B the mass of an atom of the element relative to the mass of a hydrogen atom.□ C the weighted mean mass of an atom of the element relative...
However, these are not presented as they are because they are encoded as the mass number and the atomic number. With this, it is easier to monitor the changes in the number of protons and neutrons when a nucleus undergoes a nuclear reaction....
To solve the problem, we need to determine the number of alpha (α) and beta (β) particles emitted during the radioactive decay of an element with an atomic mass number of 232 and an atomic number of 90, resulting in a lead isotope with an atomic mass of 208 and an atomic number ...
