This isotope is lead-206.
There are several, but Thallous chloride (thallium-201) is one.
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.
Iodine is an element. It comes in only one form I-127 so there are no isotopes.
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
This isotope is lead-206.
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.
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.
Iodine-131 is a radioactive isotope of the element iodine.
There is no such isotope (75) known. Iodine (atom number 53, average atomic mass 127) has 53 protons and 70 up till 82 neutrons. The lowest known isotope number therefor is 123.
Iodine-131 (not iodone) is a radioactive isotope of iodine: this isotope has important applications in the treatment of thyroid diseases.

The neptunium decay series is finished with the stable isotope thallium-205.
This is stable isotope of iodine - iodine-127.
An isotope of iodine with 74 neutrons would have a mass number of 53 +74 = 127. Therefore its symbol would be I -127 or 127 C 53. 127 and 53 should be written as superscript and subscript respectively before writing the chemical symbol of iodine when using the later (127 C 53).Ê 53 is the atomic number of iodine.ÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊ
If you use a heavier isotope of iodine, it should be radioactive.
