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.
What else can I help you with?
What is the mass number of an lead atom that has 80 neutrons?
The mass number of an atom is equal to the sum of the number of protons and neutrons in its nucleus. Since lead has an atomic number of 82 (number of protons), if the lead atom has 80 neutrons, then the mass number would be 82 (protons) + 80 (neutrons) = 162.
How many protons and electrons nd neutrons in lead?
Lead has: 82 Protons 82 Neutrons 125 Electrons
What is Z A and N if the nuclide of lead that contains 1.5 times as many neutrons as protons?
For lead, the number of protons (Z) is 82, since the atomic number of lead is 82. If the nuclide contains 1.5 times as many neutrons as protons, then the number of neutrons (N) would be 1.5 times 82, equaling 123.
What has 82 protons and 126 neutrons?
An atom with 82 protons and 126 neutrons corresponds to the element lead (Pb) in its most stable form, lead-208.
What isotope remains after the alpha decay of polonium 212?
Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
What is the mass number of lead that has 127 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Lead (Pb) has an atomic number of 82, so it has 82 protons. If it has 127 neutrons, the mass number would be 82 (protons) + 127 (neutrons) = 209.
What is the mass number of an lead atom that has 80 neutrons?
The mass number of an atom is equal to the sum of the number of protons and neutrons in its nucleus. Since lead has an atomic number of 82 (number of protons), if the lead atom has 80 neutrons, then the mass number would be 82 (protons) + 80 (neutrons) = 162.
How many protons and electrons nd neutrons in lead?
Lead has: 82 Protons 82 Neutrons 125 Electrons
What is Z A and N if the nuclide of lead that contains 1.5 times as many neutrons as protons?
For lead, the number of protons (Z) is 82, since the atomic number of lead is 82. If the nuclide contains 1.5 times as many neutrons as protons, then the number of neutrons (N) would be 1.5 times 82, equaling 123.
What element has 86 electrons 125 neutrons 82 protons?
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.
What has 82 protons and 126 neutrons?
An atom with 82 protons and 126 neutrons corresponds to the element lead (Pb) in its most stable form, lead-208.
How many neutrons does lead have?
It depends on the isotope (atoms of lead with different numbers of neutrons). There are three stable isotopes of lead:206Pb has 124 neutrons207Pb has 125 neutrons208Pb has 126 neutrons
What isotope remains after the alpha decay of polonium 212?
Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
What is the mass number for lead 206?
The mass number for lead-206 (Pb-206) is 206. This indicates that it has a total of 206 protons and neutrons combined in its nucleus. Specifically, lead-206 has 82 protons and 124 neutrons, as lead's atomic number is 82.
What If there are 128 neutrons in Pb 210 how many neutrons are found in the nucleus of Pb 206?
Lead-210 has 82 protons, so 128 - 82 = 46 neutrons in Pb-210. Lead-206 has 82 protons, so since it's a different isotope, the number of neutrons will differ. Lead-206 has 206 - 82 = 124 neutrons.
How many protons are in Lead 204?
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 is the number of neutrons in an atom of lead?
Pb (lead) 82 protons 82electrons 125 neutrons
