No, thallium isotopes do not contain iodine. Thallium isotopes are variants of the element thallium, while iodine is a separate element with its own isotopes.
Helium is chemically inert and does not combine with any other element (including thallium).
Thallium has several isotopes, with thallium-204 being stable, while thallium-201, which is commonly referenced in decay discussions, has a half-life of about 73 hours. Other isotopes, like thallium-202 and thallium-203, have half-lives of 12.3 days and 46.5 hours, respectively. The decay time varies depending on the specific isotope in question.
The ratio of isotopes are constant throughout the universe. In any random sample of any element, there will be a consistent ratio of isotopes of that element. This is what makes radiocarbon dating of ancient organic material possible.
It has 10
Thallium is a chemical element with symbol Tl and atomic number 81
Thallium has two stable isotopes: Tl-203 (29.5%) and Tl-205 (70.5%). The percentages represent the relative abundance of each isotope in naturally occurring thallium.
Thallium is a chemical element with symbol Tl and atomic number 81
Tl stands for thallium on the periodic table. Thallium is a chemical element with the atomic number 81.
Thallium.
Thallium is an element on the periodic table. It's atomic number is 81.Because it is an element, I don't understand what you mean by "its formula".The symbol for Thallium is Tl, so the formula would be Tl...If you want the formula for a compound with thallium, that's a different story.It is not a diatomic element, if that's what you meant.For more information on thallium, go tohttp://en.wikipedia.org/wiki/Thallium
Thallium is a soft, metallic element with a texture that is smooth and somewhat shiny when freshly cut.
