Cu-63 Cu-65, find the atomic mass and explain which isotope of copper is most abundant in nature.can i get a really detailed explanation please.
If you look up the atomic mass of Copper from the Periodic Table, you see the number is 63.546. This number is the weighted everage of the Cu atoms that exist in nature, and is equivalent to the number you would get if you randomly selected 100 Copper atoms in nature, weighed each of them, added their weights together, and divided by 100 to get the average weight of a Cu atom. Since 63.546 is closer to 63, than 65, that means there must be more Cu63 atoms in nature than Cu65 atoms. If there were equal amounts of Cu63, and Cu65, the atomic mass would be 64.00, and if there were more Cu65 than Cu63, the average would be closer to 65.00. Hope this helps.
