important properties. The type of atoms that material is made of is important. Materials are split up into two types‚ neutral elements and compound elements. Neutral elements have the exact same number of protons and electrons‚ thus canceling each other out and making the material neutral. The way that the atoms are arranged is also important. This determines how the element will interact with others. Lastly the way that the atoms are bonded to each other is essential. This determines the structure

God’s Favorite Elements If God has any favorite elements‚ they must be Hydrogen‚ Carbon‚ Nitrogen and Oxygen. These four elements make up the majority of all Biological compounds. Without them‚ life on this planet as we know it could not exist. Due to the bonding possibilities between and among these elements‚ literally millions of organic compounds are possible. Carbon is the backbone of all organic compounds. It forms the main structure of the molecule with Hydrogen‚ Nitrogen‚ Oxygen and occasionally
