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.
What element that has an atomic mass of 207?
Lead
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 total number of neutrons in an atom of 82Pb-207?
Neutrons = 207 - 82 = 125
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.
Why does mass number change from 211 to 207 after a decay?
because it releases energy, neutrons and neutrinos.
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 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.
Is 207 a prime number or a composite number?
207 is a composite number. Its factors are: 1, 3, 9, 23, 69, and 207
