Why is 81 the answer to how many protons and neutrons in a thallium atom?
The atomic number of thallium (Tl) is 81, which represents the number of protons in the nucleus. Since thallium is a stable element, the number of protons and neutrons in its nucleus should be equal. Therefore, the number of neutrons in a thallium atom is also 81.

How many protons and neutrons does thallium-201 have?
Thallium-201 has 81 protons and 120 neutrons. This is determined by the atomic number of thallium (81) indicating the number of protons, and the mass number of thallium-201 (201) indicating the total number of protons and neutrons. Subtraction of the atomic number from the mass number gives the number of neutrons.
