Problem #2a: Copper is made up of two isotopes, Cu-63 (62.9296 amu) and Cu-65 (64.9278 amu). Given copper's atomic weight of 63.546, something is an percent abundance of each isotope? Solution: WebThe rare carbon-14 ( 14 C) isotope contains eight neutrons in its nucleus. Unlike 12 C and 13 C, this isotope is unstable, or radioactive. Over time, a 14 C atom will decay into a stable product. The vast majority of all carbon found on Earth is 12 C. Almost 99% of all carbon on Earth is of this form. While only approximately 1% of all carbon ...
