Chemical Bonding
Ionic Bondsmade between a metal & a non-metal
Covalent Bondsmade between two non-metals
Metallic Bondsmade between two metals
|
Chemical bonds form by the attraction between the positive nucleus of one atom
and the negative electrons of another atom.
and the negative electrons of another atom.
- Atoms gain stability when they share electrons and form covalent bonds
- Lower energy states make an atom more stable
- Gaining or losing electrons makes atoms more stable by forming ions with noble-gas electron configurations (ionic bonds)
- Sharing valence electrons with other atoms also results in noble-gas electron (covalent & metallic bonds)

Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are.

Models are great, except they're also usually inaccurate. In this episode of Crash Course Chemistry, Hank discusses why we need models in the world and how we can learn from them... even when they're almost completely wrong. Plus, Lewis Structures!
