Its boiling point is the lowest among all the elements.It is a soft, silvery-white alkali metal. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:FRAN ALEXANDER , PETER BLAIR , JOHN DAINTITH , ALICE GRANDISON , VALERIE ILLINGWORTH , ELIZABETH MARTIN , ANNE STIBBS , JUDY PEARSALL , and SARA TULLOCH ",FRAN ALEXANDER , PETER BLAIR , JOHN DAINTITH , ALICE GRANDISON , VALERIE ILLINGWORTH , ELIZABETH MARTIN , ANNE STIBBS , JUDY PEARSALL , and SARA TULLOCH "am Americium dioxide (AmO 2) Interesting facts: It was discovered as a by-product of the Manhattan Project when testing the atomic bomb. The standard SI unit is,Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on,If we include man made elements, the densest so far is,The density of a material varies with temperature and pressure.
In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. 113Cd has specific absorption cross-section.Indium is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. n. Symbol Am A white metallic transuranic element of the actinide series, having isotopes with mass numbers from 232 to 247. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. It is the fourth most common element in the Earth’s crust.
