¿Qué descubrio Berta Karlik?
Investigación. Durante la Segunda Guerra Mundial hizo su descubrimiento más importante, que el elemento con número atómico 85, el astato, era producto de decaimiento natural. El principal uso del astato es en radioterapia para eliminar células cancerígenas.
What is astatine?
Astatine is a radioactive chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth’s crust, occurring only as the decay product of various heavier elements.
What is the half life of astatine?
Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth’s crust, occurring only as the decay product of various heavier elements. All of astatine’s isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours.
Does astatine have a high melting point?
Astatine undergoes sublimation but less readily than iodine and have a low vapor pressure. Its boiling point and melting point also follow the trend of this group and are higher than other members of the halogen family. Astatine is the least reactive element among its group, halogens.
