Why does the mass number change from 211 to 207 after a decay?
The change in mass number from 211 to 207 after a decay is due to the emission of an alpha particle, which consists of two protons and two neutrons. When an alpha particle is emitted during radioactive decay, the mass number decreases by 4 and the atomic number decreases by 2.
What is the total number of neutrons in an atom of 207 82 PB?
The atomic number of lead (Pb) is 82, which represents the number of protons. To find the total number of neutrons, subtract the atomic number from the mass number. For lead-207 (207Pb), the mass number is 207. Therefore, the total number of neutrons in an atom of 207 82 Pb is 207 - 82 = 125 neutrons.
What is the mass number of this element Pb 82 207.19?
Lead is a metal element. Atomic Mass number of it is 207.
What is the mass number of this element 82 pb?
Mass number refers to a particular isotope of 82Pb.
What is the number of atomic mass in lead?
Lead is a meta element. Atomic mass of it is 207.
What is the mass number lead?
Lead is a metal element. Atomic mass of it is 207.
Element with 207 as it atomic mass number?
The element with atomic mass number 207 is lead (Pb). Lead is a heavy metal that is commonly used in batteries, construction materials, and ammunition.
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
What is the mass no of lead?
The mass number of lead (Pb) varies depending on the isotope. The most stable and abundant isotope is lead-207, which has a mass number of 207. Other common isotopes include lead-206 and lead-208, with mass numbers of 206 and 208, respectively. The mass number represents the total number of protons and neutrons in the nucleus of an atom.
What is leads mass number?
Stable isotopes are 204, 206, 207, and 208. Average is 207.2.
What is the mass number of this lead atom?
... that each atom of lead contains 82 protons in its nucleus.
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.
