He was part of the team that discovered elements 97 and 98 (berkelium and californium) in 1949 and 1950. [1] Street was born in 1920 in Berkeley, California. He obtained his degree in chemistry in 1943 from the University of California, Berkeley. [1]
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]
One of the elements is Californium, which he and several others made. Thompson was also a leader of the research teams that discovered the next three transuranium elements: einsteinium, fermium and mendelevium (atomic numbers 99, 100 and 101). [1] He received Guggenheim Fellowships (Natural Sciences - Chemistry) in 1954 and 1965. [2]

Three people were found dead inside a home in Edmonson County Tuesday, according to Kentucky State Police. KSP said the Brownsville Police Department contacted them at approximately 2:40 a.m ...
Its density of 8.84 g/cm 3 is lower than that of californium (15.1 g/cm 3) and is nearly the same as that of holmium (8.79 g/cm 3), despite einsteinium being much heavier per atom than holmium. Einsteinium's melting point (860 °C) is also relatively low – below californium (900 °C), fermium (1527 °C) and holmium (1461 °C).
