Krypton, a noble gas with the symbol Kr, has a number of isotopes, but the most common one is Krypton-86. To find the number of neutrons in krypton, you first need to know its atomic number and its atomic mass.
The atomic number of krypton is 36, which means it has 36 protons. The atomic mass of the most abundant isotope, Krypton-86, is approximately 86.
The number of neutrons can be calculated using the formula:
Number of Neutrons = Atomic Mass – Atomic Number
So, for Krypton-86, it would be:
Number of Neutrons = 86 – 36 = 50
Therefore, krypton has 50 neutrons in its most common isotope, Krypton-86.
