Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]
This 1562 map Americae Sive Quartae Orbis Partis Nova Et Exactissima Descriptio by Diego Gutiérrez was the first map to print the toponym California.. Multiple theories regarding the origin of the name California, as well as the root language of the term, have been proposed, [1] but most historians believe the name likely originated from a 16th-century novel, Las sergas de Esplandián.

A 2017 state legislative document states, "Numerous theories exist as to the origin and meaning of the word 'California, '" and that all anyone knows is the name was added to a map by 1541 "presumably by a Spanish navigator." [23]
The more ambitious province name, Las Californias, was established by a joint dispatch to the King from Viceroy de Croix and visitador José de Gálvez, dated January 28, 1768. Gálvez sought to make a distinction between the Antigua ('old') area of established settlement and the Nueva ('new') unexplored areas to the north.
Its density of 14.78 g/cm 3 lies between those of curium (13.52 g/cm 3) and californium (15.1 g/cm 3), as does its melting point of 986 °C, below that of curium (1340 °C) but higher than that of californium (900 °C). [5] Berkelium is relatively soft and has one of the lowest bulk moduli among the actinides, at about 20 GPa (2 × 10 10 Pa). [6]
