Basic Information Name: Rhenium Symbol: Re Atomic Number: 75 Atomic Mass: 186.207 amu Melting Point: 3180.0 °C (3453.15 K, 5756.0 °F) Boiling Point: 5627.0 °C (5900.15 K, 10160.6 °F) Number of Protons/Electrons: 75 Number of Neutrons: 111 Classification Isotope definition is - any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. Gonadotropin‐releasing hormone (GnRH) receptor antagonists are an important class of compounds designed to block the pituitary gland from synthesizing follicle‐stimulating hormone and luteinizing hormone for the treatment of sex hormone dependent disorders. Problem #13: Rhenium has two naturally occurring isotopes: Re-185 with a natural abundance of 37.40%, and Re-187 with a natural abundance of 62.60%. The sum of the masses of the two isotopes is 371.9087.
