What are atoms? What do you think atoms do to contribute to living things? Do you think the shape of something helps to determine its function (what it does)? Why or why not? What happens if the shape of something changes? Will it still have the same function?.

Ionic/Covalent/Metallic Bonding Notes

Ionic/Covalent/Metallic Bonding Notes. Stable or Unstable?. An atom is only stable if it has a full valence shell If an atom is stable, it will not bond If an atom is not full, it will bond. Compounds. Compounds are formed when 2 atoms of different elements bond together.
