Symbol: Tl
Atomic Number: 81
Atomic Mass: 204.3833 amu
Number of Protons & Electrons: 81
Number of Neutrons: 123
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.
7 protons, 7 neutrons and 7 electrons
it has 44 electrons 57 neutrons and 44 protons
4 protons, 4 electrons and 6 neutrons.
The phosphorus atom has 15 protons and electrons and 16 neutrons.
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.
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.
