Themes Science Chemistry General Chemistry ... Atoms, Ions, and Molecules A molecule is a definite group of atoms that are chemically bonded together. They are tightly connected by attractive forces. A molecular formula is a chemical formula that gives the exact number of different types of atoms in a molecule. Some simple molecular substances are carbon dioxide, CO ; ammonia, NH ; and water, H O. The atoms that are in a molecule are not just stuffed together without any order. The atoms are chemically bonded to one another in order to form a definite arrangement. A structural formula is a chemical formula which shows how the atoms are bonded to one another to form a molecule. A good example is the structural formula for water, H-O-H. Those two horizontal lines connecting the H with the O (hydrogen and oxygen) represent the chemical bonds joining the atoms. An ion is an electrically charged particle obtained from an atom or chemically bonded group of atoms by adding or removing electrons. Now what this means is that an ion is the result of taking away, or adding, electrons to an atom or a chemically bonded group of atoms. By taking away, or adding, these electrons, the particle takes on an electrical charge. Atoms are electrically neutral as they contain an equal number of positive and negative charges. An atom that adds an extra electron to it becomes a negatively charged ion. This type of ion is called an anion. An atom which loses one or more of its electrons now has a positive charge, and is called a cation. For example, a sodium atom can lose one of its electrons and form a sodium cation. Now, instead of being Na, it would be Na

Atoms, Molecules, Water, pH We need to start with a little chemistry because living organisms are made of and use chemicals. Individual substances are called elements , substance which cannot be broken down or subdivided by ordinary chemical means. We recognize about 105 or 106 elements. About 92 are natural and the rest are man-made. These are things like oxygen, sulfur, carbon, copper, etc. Each element has a symbol made of the first letter or two of its name. Some are from the old Latin names: sodium = natrium, iron = ferrum, potassium = kalium. Of the 92 naturally-occurring, four of these make up about 96% of all living matter. These are carbon, oxygen, hydrogen, and nitrogen, and the name COHN can help you remember these. Another 21 are needed in smaller amounts in order to live and stay healthy. One piece, one particle of an element is an atom a unit of matter or the smallest possible amount of an element. Two or more atoms can bond together to form a molecule . Often the compound thus formed has properties quite different from the elements in it. For example, sodium (Na), an extremely reactive, nearly explosive metal, and chlorine (Cl), a toxic gas combine to form sodium chloride (NaCl), which is common table salt.

Atoms of different elements have different properties. In an ordinary chemical reaction, no atom of any element disappears of is changed into an atom of another element. Compounds are formed when atoms of two or more elements combine. In a given compound, the relative numbers of atoms of each kind are definite and constant whole number ratios. Chemical reactions involve reorganization of the atoms-changes in the way they are bound together. Dalton's work was based on 3 laws of chemistry Law of Conservation of Mass (Antoine Lavosier, 1789), Based on second postulate: atoms are neither created or destroyed (under normal chemical reactions). Law of Definite Proportion, (Proust's Law), Based on third postulate, atom ratio is fixed, so mass must be constant.

In liquids the particles (atoms, ions, or molecules) can move freely but remain adjacent to the other particles. In solids not only are the particles adjacent, but the motion of the particles is limited. In gases Chapter 8 ) the particles move freely and independently; that is, without attaching to other particles. The atoms, ions, or molecules are held together by intermolecular forces . All these forces are based on the attraction of a positive charge to a negative charge. The magnitude of the force ( U ) is expressed by Coulomb's law U k Q Q d ) (Equation 9.2) where Q is the charge, d is the distance between the charges, and k is a proportionality constant.

Atoms, Molecules and Ions Molecules and ions Molecules and Ions Although atoms are the smallest unique unit of a particular element, in nature only the noble gases can be found as isolated atoms. Most matter is in the form of ions , or compounds Molecules and chemical formulas A molecule is comprised of two or more chemically bonded atoms. The atoms may be of the same type of element, or they may be different. Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form " O " (two oxygen atoms chemically bonded together). Oxygen can also exist in another molecular form where three atoms are chemically bonded. O is also known as ozone. Although O and O are both compounds of oxygen, they are quite different in their chemical and physical properties. There are seven elements which commonly occur as diatomic molecules. These include H, N, O, F, Cl, Br, I. An example of a commonly occurring compound that is composed of two different types of atoms is pure water, or "H O". The
