Thallium, Tl
the name of the element is ,Lead. ;)
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.
82 protons
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
Lead has more protons in the nucleus of its atoms compared to tin. Lead has 82 protons while tin has 50 protons in its nucleus.

lead[Pb]
The element with 82 protons and an atomic mass of 166 is lead, with the chemical symbol Pb.
Lead
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.
That depends on the number of protons. It also depends whether the atom has gained or lost electrons to form an ion. Carbon is element number 6; it has 6 protons and 6 electrons. Lead is element number 82; it has 82 protons and 82 electrons.
the element is lead and the particular isotope is Pb-206
82 protons
The element with 86 electrons, 125 neutrons, and 82 protons is the element Lead (Pb). The number of protons (atomic number) determines the element, and in this case, it is 82 for lead. The sum of protons and neutrons gives the atomic mass, which is 207 in this case, making it the isotope with mass number 207.
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
Atomic Number: It is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus. Therefore, a neutral atom of Pb (lead) would have 82 protons and 82 electrons.
Lead has more protons in the nucleus of its atoms compared to tin. Lead has 82 protons while tin has 50 protons in its nucleus.
