Naturally occurring iron contains three stable isotopes, namely, 56Fe, 57Fe, and 58Fe, with isotope 56Fe, being the most abundant. Isotopes 54Fe and 59Fe are radioactive; the latter does not occur naturally. Propose the mode of decay for isotopes 54Fe and 59Fe, respectively, and write a decay equation for each isotope.

Most elements occur naturally as a mix of different isotopes. An element's atomic mass is the weighted average of the isotope masses. In other words, it is an average that takes into account the percentage of each isotope. For example, the two naturally occurring isotopes of boron are given here The atomic mass of boron is calculated as follows: (10.0 times 0.199) + (11.0 times 0.801) = 10.8 amu Because the heavier isotope is more abundant the atomic mass a...

1 (6)Uranium has three naturally occurring isotopes 22U, 235s2U, and 3 2U. The isotope Uranium-235is considered to be "weapons grade uranium" and can be used to make atomic weapons. The fractional abundances for two of the uranium isotopes are uranium-238-99.274% and Uranium-234-0.005%. The molecular mass of natural uranium is 237.9758amu. What is the fractional abundance of weapons grade uranium using these numbers (note: the number on the periodic table takes into account isotopes that aren't natural so use the numbers...
