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 ...

Lanthanumand the light lanthanides (cerium througheuropium) are more abundant than the heavy lanthanides (gadoliniumthroughlutetium). Thus, the individual light lanthanide elements are generally less expensive than the heavy lanthanide elements. Furthermore, the metals with evenatomic numbers(cerium,neodymiu...
