Mass number refers to a particular isotope of 82Pb.
The atomic number for the Element Lead is 82.
Lead is a metal element. Atomic Mass number of it is 207.
... that each atom of lead contains 82 protons in its nucleus.
The atomic number of lead (Pb) is 82, which represents the number of protons. To find the total number of neutrons, subtract the atomic number from the mass number. For lead-207 (207Pb), the mass number is 207. Therefore, the total number of neutrons in an atom of 207 82 Pb is 207 - 82 = 125 neutrons.
Lead is an element, with the chemical symbol Pb and atomic number 82.
The atomic number for the Element Lead is 82.
Atomic number 82 is Lead (Pb).
The element with 82 protons and an atomic mass of 166 is lead, with the chemical symbol Pb.
Lead is a metal element. Atomic Mass number of it is 207.
... that each atom of lead contains 82 protons in its nucleus.
Pb
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
Element 82 is lead with the symbol Pb (from the Latin "plumbum.")
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.
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
The atomic number of lead (Pb) is 82, which represents the number of protons. To find the total number of neutrons, subtract the atomic number from the mass number. For lead-207 (207Pb), the mass number is 207. Therefore, the total number of neutrons in an atom of 207 82 Pb is 207 - 82 = 125 neutrons.
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
