How many protons does thallium-201 have?
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.
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.
What particle has 78 electrons and 81 protons?
It is an atom. The only atom with 81 protons, i.e. atomic number 81, is Thallium, Tl. If it has 3 less electrons it has 3+ positive charge. So it is the Tl3+ ion. Note you usually encounter Thallium as Tl+ . In thsi respect it is different from the other members of Group 13.

How many protons neutrons and electrons in thallium?
ThalliumSymbol: TlAtomic Number: 81Atomic Mass: 204.3833 amuNumber of Protons & Electrons: 81Number of Neutrons: 123
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.
What is the composition of thallium?
