Difference Between Plato and Socrates. Plato and Socrates are two philosophers that showed differences between them when it comes to their philosophical concepts and thought. One of the primary differences between Plato and Socrates is that Plato gave a lot of importance to the soul of the human being than the body.
Overview. Astatine is a member of the halogen family, elements in Group 17 (VIIA) of the periodic table. It is one of the rarest elements in the universe. Scientists believe that no more than 25 grams exist on the Earth's surface.statine is far too rare to have any uses. Some research suggests a possible medical use, however. Astatine is similar to the elements above it in Group 17 (VIIA) of the periodic table, especially iodine.
In nature, it is formed by radioactive decay and exists in small amounts because of its short half-life. This element is, in fact, the rarest one to occur naturally, with estimates that no more than thirty grams are found in the earth's crust. Astatine is the heaviest halogen, known to men.It is believed that the metal accumulates in the thyroid gland similar to iodine. Astatine has 20 known isotopes and all of them are radioactive. Other sources point to between 7 and 33 isotopes.The most stable isotope of astatine is astatine-210. Through electron capture, it decays into polonium-210 and through alpha decay astatine-210 decays into bismuth-206. Its half-life is 8.1 or 8.3 hours.Astatine itself occurs as a result of decay of thorium or uranium.he most stable isotope of astatine is astatine-210. Through electron capture, it decays into polonium-210 and through alpha decay astatine-210 decays into bismuth-206. Its half-life is 8.1 or 8.3 hours.
