Noun
isotope (plural: isotopes)- Any of two or more atoms of an element having the same number of protons, but a different number of neutrons in its nucleus. As a consequence, it will have the same atomic number but a different mass number (atomic weight).

...A nuclide is an atomic nucleus with a specified composition of protons and neutrons. The nuclide concept emphasizes nuclear properties over chemical properties while the isotope concept does the converse; for the neutron number has drastic effects on nuclear properties but negligible effects on chemical properties. Since isotope is the older term, it is better known, and it is still sometimes used in contexts where nuclide would be more proper, such as nuclear technology. Read full entry

What is the percent abundance A hypothetical element has an
atomic weight of 69.72 amu.
The two isotopes of this
element have mass numbers of
67 and 70. What is the percent
abundance of the isotope with
the mass number of 67?
(work please too!)
i dont know what to do with
the x!!!

I won't work it but I'll give you the formula. 69.72=(67x) + (70(1-x)) x = 0.093 or 9.3 % |

What is a negative isotope Does anyone know a negative
isotope created by nuclear
power plants, that damages the
environment / human health?

I'm not sure what you mean by negative isotope, so I can't answer that part of the question. But there are plenty of isotopes created nuclear power plants that are detrimental to human health. In fact, anything radioactive is potentially bad for human health, and a nuclear reactor creates a lot of radioactive isotopes. Most of the dangerous materials are contained in the fuel elements of the reactor, although some are intentionally created outside of the fuel for research or practical purposes (for example, Co-60 is often created since it's useful for medical applications). One of the biggest concerns for reactors is the release of tritium, which is an isotope of hydrogen. Although it's half life is relatively short, so its not as dangerous as many of the other isotopes created in the fuel. FInally, there's probably millions of billions of particles that actually completely escape the reactor called neutrinos, but they don't harm anyone or anything (and there's already a massive number of them coming from the rest of the universe). All of that said, nuclear reactor actually emit fewer radioactive materials than say a coal or gas power plant |

How do you tell which Isotope For example how do you tell
which isotope, N-14 and N-15,
is more common or abundant in
nature if the atomic mass of
nitrogen is 14.007?

it's a weighted average. if the average is close to a whole number, chances are that the isotope corresponding to that mass number is most common. but this can be deceptive. for instance if you look at chlorine, which has a molar mass of 35.5, you might think that it consists of 50% Cl-35 and 50% Cl-36. but in fact it's 75% Cl-35 and 25% Cl-37. you need to know which isotopes are stable as well as their abundances. |
