Thalium is a meta element. Atomic mass of it is 204. Atomic number of it is 81.
Thalium is a metal element. Atomic mass of it is 204.
81 protons, as the atomic number of thallium is 81
No, Thalium is classified under Group 13, also known as the Boron family, Period 6, with an atomic number of 81 and is represented by "Tl".
The atomic number of thallium (Tl) is 81.The atomic weight of Tl is 204.38 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
No, it is a naturally occurring element.
thalium (Tl)
The chemical symbol is Tl for thallium.
11.85 grams per cubic centimeter
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
