Atoms

1. Nucleus

   • Neutrons: Neutral charge
   • Protons: Positive charge

2. Lewis Dot Structure

   • diagrams that represent the valence electrons of atoms within a molecule. These Lewis symbols and Lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds.

3. Octet rule

   • the tendency of atoms to prefer to have eight electrons in the valence shell.

4. Electron cloud

   • Electrons: Negative charge
