n. (Symbol Cf)
Californium is a synthetic element produced in trace quantities by helium isotope bombardment of curium. All isotopes are radioactive, chiefly by emission of alpha particles. Atomic number 98; mass numbers 244 to 254; half-lives varying from 25 minutes to 800 years.

The isotope 252Cf is a very strong neutron source; some applications are:
- neutron's detectors for water and petroleum
- control of nuclear fuel rods
- treatment of some cancers by neutron irradiation
- neutron radiography in industry
- neutron activation analysis in mobile installations

Californium has a moderate chemical reactivity - on the Pauling scale the electronegativity is 1,3 (this value is practically similar for all the actinoids).
Californium react with oxygen, sulfur, nitrogen, hydrogen, halogens, water, etc.

Chemical properties of californium:
- Pauling electronegativity: 1,3
- Valences: 3, 2, 4
- Californium can react with the majority of non metals
Having an electronegativity of 1,3 on the electronegativity scale of L. Pauling californium is a moderate reactive metal.
Californium is malleable and have a low Mohs hardness.
Californium can react with oxygen, hydrogen, sulfur, nitrogen, halogens, etc.
Being radioactive californium is unstable.
Gold ans silver (and also other chemical elements) can be detected by neutron activation analysis. Californium-252 is a neutron source for mobile NAA installations.
Elements react with other elements based on the number of electrons in their outer shell, also called valence electrons.
