W 187 isotope

Basic Information Name: Tungsten Symbol: W Atomic Number: 74 Atomic Mass: 183.84 amu Melting Point: 3410.0 °C (3683.15 K, 6170.0 °F) Boiling Point: 5660.0 °C (5933.15 K, 10220.0 °F) Number of Protons/Electrons: 74 Number of Neutrons: 110 Classification 31)At time zero, there are 10.o grams of W-187. If the half -life is 23.9 hours, how much will be present at the end of one day? Two days? Seven days? 32) 100.o grams of an isotope with a half-life of 36.0 hours is present at time zero. How much time will elapse before 50.0 grams remains? Before 5.00 grams remain?

The atomic mass is the mass of an atom.

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.
