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.
The number of protons and electrons is same as its atomic number. To find neutrons, subtract the atomic number from atomic mass.
An atom of lead has 82 protons in its nucleus.Note, the atomic number of lead is 82 and this number always equals the number of protons in the atomic nucleus (and the number of electrons the neutral atom has).
because the atomic number of lead is known to be 82 and as the equation statesatomic number=number of protons= number of electron
Lead has the atomic number of 82. The neutral atom will have the same number of electrons as it does protons, or 82.
The atomic number of lead is 82 and there are 82 protons and 82 electrons.
82 is the Atomic Number for lead and lead has 82 electrons, 82 protons and between 95 and 135 neutrons, depending on which isotope.
The atomic number of tin is 50 and the atomic number of lead is 82. The atomic number tells the number of protons in the nucleus, so lead has more protons.
Lead has six energy levels. It has an atomic number of 82 which is also equivalent to the number of protons and electrons.
The number of protons and electrons will be the same as the elements atomic number which is 82. The number of neutrons will vary with the isotope; however, the most common is 208Pb with 126 neutrons.
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
The atomic # of Lead is 82... Thus Lead has 82 protons.
Lead, (Pb) has an Atomic number of 82 (you can look this up on a periodic table).This means it has 82 Protons and a neutral atom also has 82 electrons.To find the number of Neutrons you subtract the Atomic Number (82) from the Atomic Mass (208).Therefore the number of Neutrons in this isotope of Lead is 208-82 = 126
protons:82 neutrons:126 electrons:82
Well, to keep it simple, the number of electrons is usually the number of protons in the element, which is the atomic number. For instance, hydrogen has 1 proton and 1 electron, while Lead, Pb, has 82 protons and electrons. This is, of course, when the elements are naturally occuring. There are isotopes for elements which change the number of protons or electrons, thus changing the charge.
All isotopes of lead have the same number of electrons: 82, the atomic number of lead.
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
The atomic number of lead is 82. That tells us that electrically neutral lead has 82 protons and 82 electrons. The three stable isotopes of lead are 206Pb, 207Pb, and 208Pb. These isotopes have 124, 125, and 126 neutrons per each atom, respectively.
82. The atomic number of an atom is the same as the number of electrons it has.
The atomic number of an element accounts for the number of protons in the nucleus of the atom of that element. For example: * Hydrogen atomic number is one. The nucleus of its atom has one proton. * Oxygen atomic number is 8. The nucleus of its atom has 8 protons. * Iron atomic number is 26. The nucleus of its atom has 26 protons. * Lead atomic number is 82. The nucleus of its atom has 82 protons. * Uranium atomic number is 92. The nucleus of its atom has 92 protons.
+4 On the periodic table, all elements are neutral. And that is the key to this problem. Lead (Pb) on the periodic table has an atomic number of 82. Therefore it has 82 protons. How many electrons would it need to be a neutral atom then? Obviously, 82! So if we have 82 electors and 82 protons we have neutral lead, but we don't have 82 electrons we only have 78. Therefore neutral lead lost negatively charged electrons. When you lose a negative you become more positive. So we have a charge of +4, since 82-78=4. In general the solution to this problem is: (Atomic Number) - (Number of Electrons) = (Net Charge)
... that each atom of lead contains 82 protons in its nucleus.
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.
78, lead has atomic number of 82
Lead has: 82 Protons 82 Neutrons 125 Electrons
