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.
Thallium is a chemical element with symbol Tl and atomic number 81
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.
