The most stable isotope of thallium is thallium-205, which has 81 protons and 124 neutrons. Thallium in its elemental form is a soft, malleable, heavy metal that is typically found in nature combined with other elements.
Thallium is a heavy metal that is known to be odorless. There is no distinct smell associated with thallium.
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
Thallium has 6 electron shells.
Thallium is a chemical element with symbol Tl and atomic number 81

Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
the overall atomic mass is 204.37, but for thallium 203 it is 203, and for thallium 205, it is 205.
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.
I think thallium weight about 189
Thallium has 6 electron shells.
Thallium(III) Selenide
Thallium-201 has 81 protons. This is because the number of protons in an atom is equal to its atomic number, and thallium has an atomic number of 81.
Thallium is a chemical element with symbol Tl and atomic number 81
