Yes, it is.
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!
Element 81 is thallium.
This chemical element is krypton.
the one with 81 as the smaller number.... if there isen't one, then you've got your calculations wrong...

Thallium is a meta element. Atomic number of it is 81.
Tl is element 81 Thallium, a highly toxic poor metal.
The atomic mass of the isotope with mass number 81 is approximately 81 atomic mass units (amu). This isotope corresponds to elements like thallium (Tl) or bromine (Br), depending on the context. However, if you are referring to the atomic mass of a specific element, please clarify which element you're interested in.
If thallium emits a beta particle, it undergoes beta decay and transforms into a new element called lead. This process involves the conversion of a neutron in the thallium nucleus into a proton, resulting in the formation of lead.
