Melting point elements

Astatine is located just below iodine, which suggests that it should have some of the same chemical properties as iodine, even though it also acts more hke a metal or semimetal than does iodine. It is a fairly heavy element with an odd atomic number, which assisted chemists in learning more about this extremely rare element. The 41 isotopes are man-made in atomic reactors, and most exist for fractions of a second. The elements melting point is about 302°C, its boiling point is approximately 337°C, and its density is about 7g/cm. ... [Pg.258]

Because only a few atoms of ununpentium have been produced and they exist for only a fraction of second, this metaUic elements melting point, boiling point, density, and several other properties have not been determined. [Pg.360]
