Lutetium is a rare earth metal discovered in 1906 with a melting point of 1925 K and boiling point of 3675 K. While not abundant, it is more common than silver in the earth's crust. Lutetium-176 is a radioactive isotope used to determine the age of meteorites due to its relatively high abundance and very long half-life of 38 billion years. Lutetium is usually found with yttrium and has some applications in metal alloys and catalysts, as well as medical use in treating neuroendocrine tumors.
Flerovium is a radioactive synthetic element with an atomic number of 114. It has a predicted melting point of 340 K and boiling point of 420 K. Flerovium was discovered in 1999 by the Joint Institute and Lawrence Livermore through observing approximately 80 decays of its atoms and isotopes with mass numbers between 285-289. The longest-lived isotope of Flerovium known is Fl-289, which has a half-life of approximately 2.6 seconds.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Antimony is a metallic element with an atomic mass of 121,760 u. It melts at 903.78 K and boils at 1860 K, with a density of 6.697 g/cm3. Antimony was discovered as early as 3000 BC and its largest applications are as an alloying material for lead and tin in lead-acid batteries, solders, bullets, and plain bearings due to improved properties. Antimony compounds are also used as fire retardants in many commercial and domestic products.

Its salts are rose-colored and it has characteristic absorption spectra bands in visible light, ultraviolet, and near infrared.
Darmstadtium is a synthetic element with an atomic mass of 281. It is predicted to behave as the heavier homologue to platinum based on its position in the periodic table as a member of group 10, although no chemical experiments have confirmed this. Darmstadtium was first synthesized in 1994 at the Gesellschaft fur Schwerionenforschung and is calculated to have similar properties to nickel, palladium, and platinum due to its position in the d-block.
