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 is the half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
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.
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
What are the steps in the process of calculating average in atomic mass given data about the isotopes of an element?
I can't find it
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.
What can you not find on the periodic table?
Isotopes of each element.
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 needed to find the average atomic mass of the element?
the mass of the isotopes

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.

How do you find the numbers of neutrons in an atom?
The number of neutrons in an atom is not a constant. It is equal to or greater than the number of protons, and the number of neutrons changes the atomic mass number, as the proton number is constant. Atoms with different numbers of neutrons are called isotopes. Some are stable, some are unstable, some are radioactive.
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
What are the steps in the process of calculating average in atomic mass given data about the isotopes of an element?
