Observing Crystals And Molecule

To investigate chemistry we need a background of how atoms effect chemical behavior. This is particularly true if we wish to gain an understanding of how drugs or disease effect behavior. We are aware of gravitational, thermal, electronic, atomic and nuclear physical effects on molecular behavior.

The investigation of atomic, electromagnetic and thermal behavior is part of Physics. We need to study Physics before completing our study of Chemical effects. See Diagram 12, "Awareness of Physical Effects."

A molecule is a particle consisting of two or more atoms joined to each other by means of a covalent bond . (Electrons are shared in covalent bonds.) There are a number of different ways of representing molecules. One method is called an electron-dot diagram, which shows the atoms included in the molecule and the electron pairs that hold the atoms together. Another method is the ball-and-stick model, in which the atoms present in the molecule are represented by billiard-ball-like spheres; the bonds that join them are represented by wooden sticks. A third method is called a space-filling model, which shows the relative size of the atoms in the molecule and the way the atoms are actually arranged in space.

This point in the study the brain and its bodily connections, our study can only be on a surface large scale (macroscopic) view. This limits us to observation effects that we can only speculate as to the cause until we have investigated on the smaller scale (microscopic) views.

A chemical substance is a form of atoms that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds.

A chemical substance is a form of atoms that has constant chemical composition and characteristic properties.[1] It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds. Chemical substances can be chemical elements, chemical compounds, ions or alloys.



plural noun: molecules


  1. a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

 All compounds are molecules but not all molecules are compounds. Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2) are not compounds because each is composed of a single element. Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds because each is made from more than one element

A chemical compound is a pure chemical substance consisting of two or more different chemical elements[1][2][3] that can be separated into simpler substances by chemical reactions.[4] Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms[3] that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds. Pure chemical elements are not considered chemical compounds, even if they consist of molecules that contain only multiple atoms of a single element (such as H2, S8, etc.),[5] which are called diatomic molecules or polyatomic molecules.
