What does the band of stability for atomic nuclei refer to?
The band of stability is a way of viewing which isotopes of the elements are stable. If you make a graph of number of neutrons versus number of protons of the stable isotopes, you find that the stable isotopes make a thick curved line on the graph which is called the "band of stability." The lighter elements tend to have the number of neutrons equal to number of protons. The heavier elements tend to have more neutrons than protons. The band of stability can help you to predict the behavior of unstable radioactive isotopes as well, because you can predict which decay process will move the element closer to the "band of stability" so it will have the ideal ratio of neutrons to protons.
How can you find the number of neutrons an element t has?
One quick way to find that out is to open the Wikipedia and type "Isotopes of Carbon", "Isotopes of Uranium", or whatever element you are interested in. Please note that each element has several different isotopes; the number of neutrons varies from one isotope to another.
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
Are all atoms isotopes?
They are not directly equatable terms. Strictly, every atom from from one isotope of the relevant element - some elements having few stable isotopes, others having a number and most having at least one unstable (i.e. radioactive) isotope.
What is the term for atoms of the same element that differ in their mass numbers?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Are there any isotopes for the element thallium?
im not sure. i am studing the elements @ skool but mine is silver. it is really easy to find if u search it on google. Sorry. ---- Thallium has 25 isotopes (2 stable and 23 radioactive); see the list below at the link.
What is the decay element of uranium?
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
Do all elements decay over time?
It is the unstable isotopes of elements that decay over time. All elements have an isotope or isotopes that are unstable and will decay over time. (These isotopes will be either naturally occurring or will be synthetic.) Some isotopes of some elements, however, are stable, and they will not undergo radioactive decay.To discover what's what, we have to do some homework, and what better place to start than the table of nuclides? It lists all the elemets, and all the isotopes of each element. Further, it tells us which ones are stable, which are unstable, and will also help us determine the decay mode of the unstable nuclides.

If an element had three isotopes with known masses what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope

If an element has three isotopes with known natural abundance percentages what kind of information is needed to find the average atomic mass of the element?
To find the average atomic mass of the element, you would need the mass of each isotope and their corresponding natural abundance percentages. Multiply the mass of each isotope by its respective abundance percentage, then sum these values for all isotopes to determine the average atomic mass of the element.
What is needed to find the average atomic mass of the element?
To find the average atomic mass of an element, you need to know the isotopic masses of each of its isotopes and their relative abundances. Multiply the isotopic mass of each isotope by its relative abundance, then sum these values to calculate the average atomic mass.
What is the result when you total the individual percent abundance of isotopes of a given element?
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
