Lead has more protons in the nucleus of its atoms than tin.

Here's why:

* Atomic Number: The number of protons in an atom's nucleus defines its atomic number.

* Tin (Sn): Tin has an atomic number of 50, meaning it has 50 protons.

* Lead (Pb): Lead has an atomic number of 82, meaning it has 82 protons.

Therefore, lead has 32 more protons than tin.
