What does 82 stand for on the periodic table?
Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials.
What element is atomic number 82 on the table of elements?
Lead is a chemical element with symbol Pb and atomic number 82.
Why are all elements with atomic numbers above 82 unstable?
When the mass number of the atom is greater than 82, the atoms are not stable because of the level of binding energy. The atom splits because of the force of repulsion between the particles and the new elements are formed as they reach the new configuration which is stable. …
How does the atomic number relate to where it is on the periodic table?
The atomic number equals the number of protons in an atom. The atomic number is what the periodic table is based on. So the atomic number increases with each element. The atomic mass is the sum of the protons and neutrons.
What does S stand for on the periodic table?
Sulfur – Element information, properties and uses | Periodic Table.
What element has an atomic number of 80?
Chemistry World’s Fred Campbell on the uses and abuses of element number 80, Quick silver, otherwise known as mercury.
What is the chemical symbol for gold?
What is the largest stable element?
The periodic table could be considered to end at the largest stable element, lead (atomic number 82). All elements with higher atomic numbers have unstable nuclei, because the assembled protons become too large for the strong nuclear force to hold together.
What is the least stable element?
Francium is the heaviest alkali and the least stable of the first 103 elements on the periodic table.
What element has the largest atomic mass?
