Tin is the element with the most stable isotopes, ten. Xenon is second with nine isotopes. Both Xenon and Cesium have 36 possible isotopes, but 27 of Xenon's and 35 of Cesium's isotopes are radioactive. This means that they decay over time and "shed" particles. Hydrogen has the smallest amount of isotopes, with three total and two stable isotopes.
What else can I help you with?
What is Isotope purity?
If an element has one and only one stable isotope, an example is Gold.
What is the Heaviest isotope of cobalt?
The only natural isotope of Cobalt is Cobalt-59.
What is the lightest element without a stable isotope?
The lightest element without a stable isotope is Technetium (atomic number 43). All of its isotopes are radioactive, with none occurring naturally on Earth.
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 Isotope purity?
If an element has one and only one stable isotope, an example is Gold.
What is the Heaviest isotope of cobalt?
The only natural isotope of Cobalt is Cobalt-59.
An element with the same number of protons and electrons as another atom of the element but with a different number of neutrons?
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable
Is Cs a radioactive element?
No, it has only one stable isotope.
What is the lightest element without a stable isotope?
The lightest element without a stable isotope is Technetium (atomic number 43). All of its isotopes are radioactive, with none occurring naturally on Earth.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
Definition of elements that are stable?
This is an element (more exactly an isotope) which is not radioactive.
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.
Is All isotopes of a given element are radioactive?
No. The most common isotope(s) of an element are often stable.
What is the largest natural stable element?
Bismuth Francium has the largest atom - the greatest atomic radius.
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 does it mean when you say an element is stable?
This element (more correct in this case is isotope) doesn't suffer a radioactive disintegration.
