What is the mass number of this element 82 pb?
Mass number refers to a particular isotope of 82Pb.
What is the mass number of this lead atom?
... that each atom of lead contains 82 protons in its nucleus.
What is the atomic number of this element of PB?
The atomic number for the Element Lead is 82.
What element appears directly below tin on the peridic talbe?
lead number 82
What is the mass number of lead that has 127 neutrons?
209 since Lead is 82.
What is the mass number of this element 82 pb?
Mass number refers to a particular isotope of 82Pb.
How many electrons are in lead outer shell?
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
What is the mass number of this lead atom?
... that each atom of lead contains 82 protons in its nucleus.
What has 86 electrons125 neutrons and 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.
What is the mass number of the element lead?
I cannot answer this question.
What is the atomic number of this element of PB?
The atomic number for the Element Lead is 82.
How many neutrons are in the average atom having an atomic mass of 207.2 grams per mole?
Look on the periodic table for the element with the closest atomic mass to that number. It's lead (Pb, #82.) Now, for the neutron count, you round that atomic mass to the nearest whole number, which is 207, then subtract the atomic number of 82 from it. 207-82=125. So 125 neutrons.
What element has 82 protons and 126 neutrons?
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.
What is the name of the element with the atomic number of 82?
Element 82 is lead with the symbol Pb (from the Latin "plumbum.")
Does a radioactive element become stable after its mass number become less than 82?
Not always -- Hydrogen-3 is radioactive, for example.
How many neutrons does Krytpon-82 have?
The answer to how many neutrons an atom of an isotope has is always the difference between the mass number of the isotope and the atomic number of the element. The atomic number of krypton is 36. Therefore, an atom of krypton-82 has 46 neutrons.
What atomic number of the element lead indicates that each atom of has lead?
82 protons
