Chemistry apid Just what you need to know! eview Valency is the number of hydrogen atoms that can combine with (or displace) one atom of the element to form a compound. For example, two atoms of hydrogen combine with one atom of oxygen to form water (H O); so, the valency of oxygen is two. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element is always a whole number. Some elements exhibit more than one valency, i.e., they have variable valency. In Iron [II] sulfate or ferrous sulfate, i.e., FeSO , the valency of iron is two. In Iron [III] sulfate or ferric sulfate, i.e., Fe

Chemistry apid Just what you need to know! eview Scientists have adopted certain conventions regarding the chemical symbols for various elements. The symbol is the short form or abbreviated name of the element. Each element has a chemical symbol that is unique to it. An atom of an element is denoted by this symbol. For example, the symbol for Carbon is C. Many elements have their symbol derived from either the first letter [e.g., H for Hydrogen] or the first two letters [e.g., He for Helium] of their names. A few elements have symbols derived from their Latin names as given in the table below.

It allows the user to predict, interpret, rationalize, and often simplify complex theory and data. At its heart is the fact that the Set of Operations associated with the Symmetry Elements of a molecule constitute a mathematical set called a Group . This allows the application of the mathematical theorems associated with such groups to the Symmetry Operations All Symmetry Operations associated with isolated molecules can be characterized as Rotations: (a) Proper Rotations : C n k ; k = 1,......, n

Extractions: The Periodic Table of the Elements It is not difficult to find periodic tables of the chemical elements. What is provided here, however, is a table with information drawn from different sources that may not always be found together (though there is the massive Handbook of Chemistry and Physics , edited by Robert C. Weast and Melvin J. Astle, of which I have the 62nd edition, 1981-1982, CRC Press, Inc.). Thus, atomic isotopes, half-lives, and decay modes are largely taken from Subatomic Physics , by Hans Frauenfelder and Ernest M. Henley (Prentice-Hall, Inc. 1974). Cosmic abundance of elements is taken from the Realm of the Universe , by George O. Abell (Holt, Rinehart, and Winston, Inc. 1976Abell's catalogue of galaxy clusters has now enshrined his name to the far reaches of the universe). Some minerological information comes from An Introduction to Minerology for Geologists Manual of Minerology Many of the sources above may seem somewhat out of date, but they reflect the period when I was studying these matters, and when I was especially intrigued to supplement a chemical view of the elements with a picture of the variety of nuclear isotopes. This table is not intended, therefore, as a resource for chemistry, physics, or minerology students. It is a resource for philosophy of science, illustrating basic ideas and information, where the most up to date data and the provision of all chemically useful information is not necessary: Data for reflection and theory, not for application and experiment. Some commentary, color coding, and further footnotes will be added.

Extractions: The Biology Web (Home) General Biology 1 General Biology 2 Human Biology Chapter 4 - Chemistry Matter occupies space and has weight. It can exist as a solid, liquid, or gas. It may be possible to break some kinds of matter down into other kinds of matter with different properties. For example, water (H O) can be broken down into hydrogen and oxygen. Hydrogen and oxygen in the above example cannot be broken down any further because they are elements Elements cannot be broken down into substances with different properties. For example, water (H O) is not an element because it can be broken down into hydrogen (H) and oxygen (O). Substances that are composed of two or more elements are called compounds . For example, water is a compound because it is composed of hydrogen and oxygen. The smallest particle of an element is an atom Elements are substances made up of only one kind of atom. There are 92 naturally occurring elements. Matter is therefore composed of 92 different kinds of elements. The following elements make up 96% of the body weight of organisms: Oxygen, Carbon, Hydrogen, Nitrogen.
