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.

∙ 13y agoLead (Pb) posses the heaviest, stable isotope, {208}Pb.
However there are theories ("Island of stability") of super heavy stable isotopes, which occurred at specific times in the early universe. There is work to recreate such states for heavier isotopes than {208}Pb.

∙ 10y agoThere are many elements that have only one "naturally abundant" isotope. These are known as Mononuclidic elements.
However, elements can form additional isotopes when exposed to radiation or bombarded in a fusion process. Some very short lived isotopes may also exist in disintegration chains of radioactive elements.
The mononuclidic elements are:
Beryllium, Fluorine, Sodium, Aluminum, Phosphorous, Scandium, Manganese, Cobalt, Arsenic, Yttrium, Niobium, Rhodium, Iodine, Cesium, Praseodymium, Terbium, Holmium, Thulium, Gold, Bismuth, Thorium, Protactinium

What is the lightest element without a stable isotope?
Technetium
What is Isotope purity?
If an element has one and only one stable isotope, an example is Gold.
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.
What is the atomic mass of roentgenium?
The atomic mass of the most stable isotope of Roentgenium is 281. This most stable isotope decays in around 36seconds. Oddly, it's most stable isotope has the same atomic mass as the most stable isotope of the element before: Darmstadtium.
How long did element 112 stay stable for?
The most stable isotope is 285Cn, which has a half life of 30 seconds. The least stable isotope is 277Cn, which has a half life of 0.7 milliseconds.

Is Cs a radioactive element?
No, it has only one stable isotope.

Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
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
Definition of elements that are stable?
This is an element (more exactly an isotope) which is not radioactive.
How long did element 112 stay stable for?
The most stable isotope is 285Cn, which has a half life of 30 seconds. The least stable isotope is 277Cn, which has a half life of 0.7 milliseconds.
Is All isotopes of a given element are radioactive?
No. The most common isotope(s) of an element are often stable.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
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.
