known as the “Grandfather of Russian Chemistry”. In St. Petersburg, he wrote his first scientific paper, “The Analysis of Finnish Allanite and Pyroxene”, this paper led to his curiosity of building the periodic table. He graduated in 1855, where he won a gold medal for being first in his class. After a few years, Mendeleev’s thesis On Specific Volumes and The Structure of Siliceous Combinations, resulted in him being able to teach theoretical and organic chemistry at the University of St. Petersburg

chemists, Ida Noddack-Tacke, Walter Noddack and Otto Berg, whom had published an article stating the discovery of “Masurium” in 1925, however at the given time because they were unable to verify the existence of “Masurium,” the International Union of Pure and Applied Chemistry excluded their discovery. It was believed that Masurium was presumably Technetium due to the chemical properties and atomic number being very similar. Technetium was later discovered and proved in the form of Technetium-97 by
Introduction During the Earth’s known existence, many raise questions to a substance that is a vital necessity to our life here. Some even may claim that the start of our lives may have occurred and begun in a single drop of this universal solvent. This mysterious compound, which may have led to our development and the survival of our existence what, is it? This is H2O, or as we call it, Water. This vital life form covers over 70 percent of the Earth, and makes up about 70 percent of our body as
compounds In order to maintain living conditions, organisms must synthesize numerous carbon-based molecules such as protein, fats, sugars, cellulose, etc. Since all the sources of carbon compounds came from living organisms, chemistry of carbon was called organic chemistry. 23.3 So many organic compounds Why So Many? The bonding Behavior of Carbon: For electrons available for bonding, electrons can be shared in four covalent bonds Carbon atoms can be linked together to form chains of
The various activities of human beings affect adversely all environments where the plants, the animals and the humans live (Kaya et al., 2002). The numbers of chemicals which are the most important group of environmental pollution were limited to a few thousand until the beginning of this century and the majority part of that was constituted by plants, animals and mineral origin accounted for natural ingredients. The production of the chemicals which were 7 million tons in 1950 is estimated to reach
The Philosophy of Science in Consilience, by E. O. Wilson, Life is a Miracle by Wendell Berry and Zen and the Art of Motorcycle Maintenance by Robert Pirsig Introduction The plot where the fields of science, ethics and religion intersect is fertile for study, and the crops it yields often represent the finest harvest of an individualís mind. In our time, modern philosophers of science have tilled this soil and reaped widely differing and important conclusions about the nature of humankind, its
