Which new element would form if lead (Pb) went through alpha decay?

Alpha decay is the loss of two protons and two neutrons from a nucleus. This decreases the total mass number by
4
and the atomic number by
2
.
In the form of an equation this is
218
84
Po
→
214
82
X
+
2
2
He
Looking at the periodic table we can find that element number
82
is lead,
Pb
, so the product element
X
is
Pb
.
