What is the mass number of Pb82?
An element, such as lead with its 82 protons per atomic nucleus, does not have a mass number, although it does have an average atomic mass, which for lead is 207.2. This is constituted from four lead isotopes that are radioactively stable. The isotopes have mass numbers of 204, 206, 207, and 208.
What is the atomic weight of gold and lead?
The atomic number of lead, Pb, is 82. Its atomic mass depends on the isotope, as the number of electrons can vary. Its atomic weight (average relative mass ) on the periodic table is 207.2.
The molar mass of a mole of lead?
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
What one has more mass an atom of gold or lead?
The atomic weight/mass of Lead is 207.19 --- --- --- The atomic weight/mass of Gold is 196.96655 --- --- --- --- --- --- Therefor Lead has more mass.
How many electrons dose lead 207 have?
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 atomic mass in lead?

Element with 207 as it atomic mass number?
Lead
What is the mass number of Pb82?
An element, such as lead with its 82 protons per atomic nucleus, does not have a mass number, although it does have an average atomic mass, which for lead is 207.2. This is constituted from four lead isotopes that are radioactively stable. The isotopes have mass numbers of 204, 206, 207, and 208.
What element has 82 protons and 126 neutrons?
Mass number is found by adding the number of protons plus the number of neutrons. Electrons are not added because they are so minute that their masses have almost no bearing on the total mass of the atom. In this case, the mass number would be about 214.
What is the mass number of an lead atom that has 80 neutrons?
162
How many neutrons are in lead with a mass number of 210?
Number of neutrons = Mass number - atomic number = 210 - 82 = 128
