Making an Ionic Compound and Lewis Dot Structure
Before you begin you will need to know:
Ions- an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
When a highly electronegative atom and an electropositive one are bonded together, an electron is transferred from the electropositive atom to the electronegative atom to form a cation and an anion, respectively. The cation, being a positively charged ion, is attracted to the negatively charged anion.
How ionic compounds form and why:
Ionic bonds form when an atom loses electrons and becomes a cation. The other atom being bonded gains the electron and becomes the anion. These two then bond to become stable. Atoms bond together to become stable and have 8 electrons together. If they can't make eight then they just share so that they have even numbers of electrons.
Metallic Bonding:
When two metals bond together they don't actually become one. Instead of one atom giving up electrons and the other atom taking the electrons they just share them. This sharing of electrons is represented by the ELECTRON SEA MODEL. The electron sea model shows a bunch of positive metal atoms with a "sea" of electrons surrounding them.
