82 protons
Isotopes of any element are those atoms which have the same no. of protons and electrons as the usual atom of that element but have extra neutrons.
This makes their mass greater than the usual atoms of that element.
Lead (Pb) has four stable isotopes - 204Pb, 206Pb, 207Pb, 208Pb. All these contain different no. of neutrons.
The amount of protrons that the element has.
The atomic number for the Element Lead is 82.
All isotopes of lead contain 82 protons and electrons; the number of neutrons is different.
82 protons
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
The atomic number is the number of protons in the nucleus of one atom of the element.
It is equal to the no. of electrons in the atom. It is called the atomic number.

The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
It indicates the atomic number of that element.
The atomic number is the number of protons in an atom of an element.
The number of protons in an atom of an element is equal to the number of electrons and is referred to as the ATOMIC NUMBER of that element.

The atomic number of an element indicates the number of protons that are located in the nucleus of an atom of that element.
The atomic number is the number of protons in the nucleus of one atom of the element.
Atomic number indicates the amount of protons present in the nucleus of an atom.
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
It is equal to the no. of electrons in the atom. It is called the atomic number.
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
The atomic number is the number of protons and defines an element. It really only indicates the element of a given atom which can be linked to other properties such as atomic mass or location on the periodic table and anything else knowing the element tells you.
