Johann Arfvedson discovered lithium in 1817 in a petalite ore found in Sweden. However, the highly reactive nature of lithium prevented its isolation until W.T. Brande and H. Davy used electrolysis on lithium oxide.
Atomic number (number of protons in the nucleus): 3 Atomic symbol (on thePeriodic Table of Elements): Li Atomic weight (average mass of the atom): 6.941 Density: 0.534 grams per cubic centimeter Phase at room temperature: Solid Melting point: 356.9 degrees Fahrenheit (180.5 degrees Celsius) ...
aon descending a group in the periodic table such as lithium,sodium,potassium,rubidium,caesium,the size of the atoms increases due to the effect of extra shells of electrons being added;this outweighs the effect of increased nuclear charge 在周期表里下降一个小组例如锂,钠,钾,铷,铯,原子增量的...
Lithium is the lightest metal in the periodic table (it will float on water, though not for long, because it is also one of the most reactive and turns rapidly into lithium hydroxide), and its atoms have three electrons. Two are tightly bound to its nucleus but the third is easily dislo...
Standard state: solid at 298 K Appearance: silvery white/grey Classification: Metallic Group in periodic table: 1 Group name: Alkali metal Period in periodic table: 2 Block in periodic table: s Shell structure: 2.1 CAS Registry: 7439-93-2Lithium...
Although these complexes were classified as alkali metal salts, but owing to the special position of lithium in the periodic table, the properties of lithium and hydrogen resemble each other in certain respects. On this basis we con-潘家来袁群盛怀禹陈国飞刘昶科学通报(英文版)...
CharacteristicsWhile classified as an alkali metal, lithium also exhibits some properties of the alkali earthmetals found in group 2 (IIA). Lithium is the lightest in weight and softest of all the metalsand is the third lightest of all substances listed on the periodic table, with an average ...
