What else can I help you with?
What is the lightest element on the periodic table with no stable isotopes?
The lightest element on the periodic table with no stable isotopes is hydrogen. It only has one proton in its nucleus and no stable isotopes.
What is Isotope purity?
If an element has one and only one stable isotope, an example is Gold.
What is protium?
Protium is the name of a common hydrogen isotope. This isotope has a single proton and does not have any neutrons.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
Does the atomic number of an element determine its mass?
Not by itself. The mass number is the sum of the numbers of protons and neutrons in he nucleus for each isotope of the element, or for elements with more than one stable isotope is an average depending on the natural abundance of the stable isotopes of the element.
What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
What is the lightest element on the periodic table with no stable isotopes?
The lightest element on the periodic table with no stable isotopes is hydrogen. It only has one proton in its nucleus and no stable isotopes.
What is Technium 99?
I suspect you mean technetium 99. Technetium is a radioactive element (atomic number 43 on the periodic table). It is the lightest element with no stable isotope, and as such is used frequently in medicine. See the Wikipedia article for more details.
What is Isotope purity?
If an element has one and only one stable isotope, an example is Gold.
Is Cs a radioactive element?
No, it has only one stable isotope.
What is protium?
Protium is the name of a common hydrogen isotope. This isotope has a single proton and does not have any neutrons.
What makes a radio active decay chain end?
A radioactive decay chain ends when a series of radioactive isotopes transforms into a stable isotope, which no longer undergoes further decay. Each isotope in the chain decays into another isotope or element until a stable state is reached. Once the final stable isotope is formed, the chain ceases, as there are no further radioactive transformations. This stable isotope can exist indefinitely without undergoing radioactive decay.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
What is unusual about hydrogen's atomic structure?
The hydrogen-1 isotope is the only known radioactively stable isotope with no neutrons.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
Definition of elements that are stable?
This is an element (more exactly an isotope) which is not radioactive.
Is All isotopes of a given element are radioactive?
No. The most common isotope(s) of an element are often stable.
