Lead shielding - Wikipedia

Lead's high density is caused by the combination of its high atomic number and the relatively short bond lengths and atomic radius. The high atomic number means that more electrons are needed to maintain a neutral charge and the short bond length and a small atomic radius means that many atoms can be packed into a particular lead structure.
