[Q]: Information: - Astatine is a radioactive chemical element with the chemical symbol At and atomic number 85, and is the rarest naturally occurring element on the Earth's crust. It occurs on Earth as the decay product of various heavier elements. All its isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. Elemental astatine has never been viewed because any macroscopic sample would be immediately vaporized by its radioactive heating. It has yet to be determined if this obstacle could be overcome with sufficient cooling. - Alchemy is a philosophical and protoscientific tradition practiced throughout Europe, Egypt and Asia. It aimed to purify, mature, and perfect certain objects. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble" ones (particularly gold); the creation of an elixir of immortality; the creation of panaceas able to cure any disease; and the development of an alkahest, a universal solvent. The perfection of the human body and soul was thought to permit or result from the alchemical magnum opus and, in the Hellenistic and western tradition, the achievement of gnosis. In Europe, the creation of a philosopher's stone was variously connected with all of these projects. - Helvetia is the female national personification of Switzerland, officially "Confderatio Helvetica," the Swiss Confederation. The Goddess Helvetia or the Goddess Helvetica. - Alice Leigh-Smith (nee Prebil) was an English nuclear physicist. She married Philip Leigh-Smith, the son of the Arctic explorer Benjamin Leigh-Smith, in 1933. She was a student of Marie Curie and was the first British woman to receive a PhD in nuclear physics. She, together with Walter Minder, announced the discovery of element 85 (now called astatine) in 1942. They proposed the name anglohelvetium for the new element. Later it was proven that in fact Walter Minder had not discovered element 85. Leigh-Smith was also involved in the use of radioactive substances as a treatment for cancer. - A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, "Z"). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up Earth, while oxygen is the most common element in the Earth's crust. - A chemist (from Greek chm (ia) alchemy + -ist; replacing chymist from Medieval Latin alchimista) is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. The word 'chemist' is also used to address Pharmacists in Commonwealth English. - Walter Minder ( August 6 . 1905 -- April 4.1992 ) was a Swiss mineralogist and chemist . He together with Alice Leigh - Smith announced the discovery of element 85 ( now called astatine ) in 1940 and 1942 . He proposed the name helvetium in 1940 and anglohelvetium in 1942 for the new element . Later it was proven that in fact he had not discovered element 85 . - Helvetium was the suggested name of chemical element number 85, now known as astatine, given to it by the Swiss chemist Walter Minder. Walter Minder announced the discovery in 1940. He chose the name based on "Helvetia", the Latin name for Switzerland, to honor his country of birth. - Pharmacists, also known as chemists (Commonwealth English) or druggists (North American and, archaically, Commonwealth English), are healthcare professionals who practice in pharmacy, the field of health sciences focusing on safe and effective medication use. A pharmacist is a member of the health care team directly involved with patient care. Pharmacists undergo university-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers.

Problem: Information: - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection. - Ecuador, officially the Republic of Ecuador (which literally translates as "Republic of the Equator"), is a representative democratic republic in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean to the west. Ecuador also includes the Galapagos Islands in the Pacific, about west of the mainland. - The Bay of All Saints, also known as All Saints' Bay and Todos os Santos Bay, is the principal bay of the Brazilian state of Bahia, to which it gave its name. Todos os Santos Bay sits on the eastern coast of Brazil, surrounding part of Bahia's capital Salvador and opening to the Atlantic Ocean. It covers , making it the largest bay in Brazil. - Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernandez, Salas y Gomez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty. - The Pardo River ( Bahia ) is a river of Bahia state in eastern Brazil . - Bahia is one of the 26 states of Brazil and is located in the northeastern part of the country on the Atlantic coast. It is the 4th-largest Brazilian state by population (after Sao Paulo, Minas Gerais, and Rio de Janeiro) and the 5th-largest by area. Bahia's capital is the city of Salvador (formerly known as "Cidade do Sao Salvador da Bahia de Todos os Santos", lit. ""City of Holy Savior of All Saints Bay""), located on a spit of land separating the Bay of All Saints from the Atlantic. Once a monarchial stronghold dominated by agricultural, slaving, and ranching interests, Bahia is now a major manufacturing center whose last three elections have been dominated by the Workers' Party. What is the relationship between 'pardo river ' and 'atlantic ocean'?
