∙ 7y agoThe 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.

∙ 13y agoThe 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.

What does the number of neutrons determine?
they determine the atomic mass of the atom
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
How many electrons does an atom of lead contain?
Lead has 82 Protons, 82 Electrons, and 125 Neutrons. It also has a melting point of 327.5 degrees C (or621.5 degrees F)
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
What is the mass number of an lead atom that has 80 neutrons?
162
How many neutrons are in a normal number of led?
Lead has 125 Neutrons in each normal atom that is not an isotope.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What is lead is made from?
Lead is an atom consisting of 82 protons and 82 electrons. The number of neutrons depends on the isotope of lead. Pb-207 isotope has 125 neutrons (207 - 82 = 125)
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What does the number of neutrons determine?
they determine the atomic mass of the atom
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
What is the name of the number neutrons of an atom?
Of course, number of neutrons or neutron number !
How do you find the neutrons for an atom?
Neutrons = Mass number - Number of Protons
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
