Electromagnetic Force and Change

This is part one on how electromagnetic force causes change. I wanted to read some other peoples blogs before I gave my full answer, but so far no one has posted. The way it seems to me, electromagnetic force causes atoms to bond into compounds or molecules. This is either by Ionic, Metallic, or Convalent bonding. In any of those cases, opposites attract. (In Ionic, the metal gives away an electron to a non-metal. Now the metal is negatively charged and the Non-metal is positive, so they attract. In convalent, the atoms share negatively charged electrons which are pulled in opposing directions by the two positively charged nuclei, so it stays together. I am still a little confused about metallic bonding. I know it deals with positively charged metal ions and negatively charged electrons...) These molecules or compounds then combine to make up everything in our world. This changes an element into a substence such as wood, clay, or air. This force also changes sad atoms into happy atoms by giving them a full valence shell. Hopefully I can add to this after I read some other peoples ideas, but this is what I've come up with so far. ( I found most of this information in our textbook and notes packet, as well as conferring with my group members, Meghan, Subbu, and Adam.)
