Thallium, discovered in 1861, does occur naturally, but not in its pure form.
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 naturally occurring element in the Earth's crust. It is not a man-made element.
Astatine is an element that does not occur naturally in large quantities on Earth.
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.

(203 x 0.30) = 60.9 (205 x 0.70) = 143.5 60.9 + 143.5 = 204.4 The answer is 204.4 amu !

Astatine is an element that does not occur naturally in large quantities on Earth.
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.
94 kinds of atoms occur naturally on earth
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.
