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".
To calculate the atomic mass of thallium, you need to consider the weighted average of the isotopes of thallium found in nature, based on their abundance. You multiply the mass of each isotope by its relative abundance, then sum these values to get the atomic mass. The atomic mass of thallium is approximately 204.38 grams per mole.
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!
this elemnt has an atomic number that is double the atomic number of silicon?
11.85 grams per cubic centimeter
The chemical symbol is Tl for thallium.
thalium (Tl)
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.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
