The isotopes 252Cf and 251Cf.
Being radioactive californium is unstable.
The most important isotopes of californium are: Cf-252, Cg-249, Cf-250.
No. The most common isotope(s) of an element are often stable.
Isotopes of a element are simply versions of that same element with different count of neutron, with that in mind they take all of the isotopes of a specific element and average them together taking in account the percent abundance of each so the most common isotope is the one on the periodic table.
The most common ionic charge of Californium is +3. Californium typically loses three electrons to achieve a stable configuration.
The atomic number of californium is 98. The atomic mass of the most stable isotope - 251Cf - is (251) after IUPAC.
Californium can react with oxygen, hydrogen, sulfur, nitrogen, halogens, etc.
Tin or Stannum with 10 stable isotopes
The Most common isotopes of elements with 14 & 15 neutrons are, respectively, silicon & phosphorus.
Californium is a synthetic element with the atomic number 98 and symbol Cf. It is a radioactive metal that is typically produced in nuclear reactors. At room temperature, Californium would likely be in a solid state, as most metals are solid at room temperature.
