Atomic Number 26
Aluminium-26 (26 Al, Al-26) is a radioactive isotope of the chemical element aluminium, decaying by either positron emission or electron capture to stable magnesium-26.The half-life of 26 Al is 7.17 × 10 5 years. This is far too short for the isotope to survive as a primordial nuclide, but a small amount of it is produced by collisions of atoms with cosmic ray protons. 26 Iron, atomic number 26, has four naturally occurring isotopes. Next Example They are: Fe-54, Fe-56, Fe -57, and Fe-58. From the table, we can see the number of neutrons in each isotope’s nucleus. Download software macbook.
