This is actually a very, very easy question to answer. Now, all atoms of the same element have the same number of protons. Otherwise, they wouldn't be the same element. For instance, if lead had one more proton, it would be bismuth, a non-toxic shiny metalloid. If it had one less, it would be thallium: a deadly poison which was only recently found. Lead has 82 protons.
When the number is given by an element name (e.g. lead-204), it is also showing the atom's nucleus' mass number. Natural lead contains lead-204, lead-206, lead-207, and lead-208. Each of these contains the same number of protons, but different numbers of neutrons, hence the mass difference. To find the number of neutrons, N, we subtract the number of protons, Z, from the mass number, A.
So, 204 - 82 = 122.
Lead-204 contains 122 neutrons.
What else can I help you with?
How many protons are in mercury-204?
There are 80 protons in mercury-204 because the atomic number of mercury is 80, which is equal to the number of protons in its nucleus.
What would happen if lead -206 lost 2 protons and 2 neutrons?
Lead has atomic number 82, if it loses 2 protons and 2 neutrons (ie an alpha particle) it becomes mercury with atomic number 80. Only lead-204 (1.4 percent of natural lead) and lead-210 (trace only) appear to do this, and 204 has such a long half life that it is regarded as stable, so your postulated reaction does not seem to be typical of lead as a whole.
