See the Related Questions link. The answer to that question contains a list of the nuclides of lead, both stable and radioactive. All lead nuclei have 46 protons. The various mass numbers are listed in the answer linked to the left of this answer.

How many radioactive elements are found in nature?
As of 2008, there were about 3200 different known nuclides. Of these, only 266 are considered stable (non-radioactive) nuclides. Therefore, there are about 2934 radioactive nuclides in nature. Some elements have multiple stable nuclides. The number of elements with at least one stable nuclide is 80. (Source: Fundamentals of Nuclear Science and Engineering, Shultis & Faw, 2008, CRC Press) The following site has a complete table of the known nuclides that is easy to view. The stable (non-radioactive) nuclides are shown in grey boxes. http://en.wikipedia.org/wiki/Table_of_nuclides_(complete) For more detailed information, refer to the following interactive table of nuclides. There is a Help screen and a handy Glossary.

Do all elements have a half-life?
Yes. From a technical point of view, all elements have isotopes (nuclides) that are radioactive and therefore have half-lives. But the majority of these are artificial - man made, and do not occur in nature on Earth. Even hydrogen has nuclides of deuterium and tritium, deuterium is stable and natural, and tritium has a half life of 12.33 years. Having said that, there are a number of nuclides that are stable and occur naturally.
Asked in Chemistry, Elements and Compounds
Do all elements have half lives why or why not?
The term only makes sense for unstable (radioactive) nuclides. All elements do have radioactive nuclides, though some don't have any stable nuclides. It's also just barely possible that protons are not stable over the extremely long term, though if so their half-lives are much, much longer than the current age of the universe. If this is true, then all elements are technically "radioactive."
