The only stable caesium isotope is 133Cs, with 78 neutrons.
How many neutrons are there in strontium Sr?
49 neutrons
Sr has 87-38 = 49 neutrons. Isotopes of elements have different numbers of neutrons. Strontium has an infamous isotope 90Sr that is a radioactive product of nuclear fission.
How is strontium-90 contained?
Strontium-90 is produced commercially through nuclear fission. Fissioning that occurs without any outside cause is called “spontaneous fission.” for use in medicine and industry. It also is found in the environment from nuclear testing that occurred in the 1950s and 1960s as well in nuclear reactor waste.

How many neutrons are in hydrogen?
no neutron
Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
