Electron Distribution In A Bond
524 wordsChemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds, we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive elec...

Chemical Compound
565 wordsBiochemistry What is Biochemistry? Biochemistry is everything from the elements to dehydration synthesis. What is an element? An element in a pure substance that can be broken down in to smaller units called protons neutrons and electrons. There are over 100 elements on our planet. Did you know that DNA is a nucleotide because of it basic structural units which contains sugars joined together to form what looks like a winding ladder? Elements can be bonded either by covalent bond, ionic bond, pe...

296 wordsLinus Carl Pauling Linus Carl Pauling was born in 1901 and died in 1994. He was an American chemist and physicist, whose investigations into the structure of molecules led to discoveries of how chemicals bond. Pauling was born in Portland, Oregon, on February 28, 1901, and educated at Oregon State College and the California Institute of Technology (Caltech). He began to apply his insights into quantum physics as professor of chemistry at Caltech, where from 1927 to 1964 he made many of his disco...

Electronic Charge Density Distribution
675 wordsThe beginning student of chemistry must have a knowledge of the theory which forms the basis for our understanding of chemistry and he must acquire this knowledge before he has the mathematical background required for a rigorous course of study in quantum mechanics. The present approach is designed to meet this need by stressing the physical or observable aspects of the theory through an extensive use of the electronic charge density. The manner in which the negative charge of an atom or a molec...
