Californium has a metallic luster, making it appear shiny. However, due to its radioactivity and the fact that it is mostly produced in labs, californium is not commonly seen or handled in its pure form.
Californium was discovered in 1950.
Californium is a member of the actinoids family with the atomic number 98.
Californium can react with the majority of non metals.
Yes, many laboratories in the world make studies on californium and on the applications of Cf.
Californium react with oxygen, nitrogen, sulfur, hydrogen, halogens, etc.
When californium emits an alpha particle, it creates curium.

Glenn T. Seaborg did not make californium himself; it was discovered by a research team at the University of California in 1950. The element was first synthesized by bombarding curium-242 with alpha particles to produce californium-245. Seaborg played a key role in the discovery and identification of californium, as well as in its naming after the state of California.
Not californium, but neutrons emitted by californium.
Protons, neutrons and electrons
All the isotopes of californium are radioactive, artificial and unstable.
