Ionic Bonding
Ionic Bonding
The bond formed between a metal and a non-metal. Electrons are transferred, forming ions with opposite charges that attract.
Covalent Bonding
Covalent Bonding
Atoms sharing electrons to achieve a full outer shell.

Study Notes
Atomic Bonding
- Atoms bond to achieve greater stability, gaining a full outer electron shell.
- Three main types of bonding: ionic, covalent, and metallic.
Ionic Bonding
- Occurs when metals and nonmetals react, transferring electrons.
- Forms ions (charged atoms/groups), with opposite charges.
- Electrostatic forces attract the oppositely charged ions, creating the bond.
Covalent Bonding
- Nonmetal atoms share electron pairs.
Metallic Bonding
- Occurs in metals and metal alloys (mixtures of metals).
Ions
- Formed by gaining or losing electrons to achieve a full outer shell.
- Negative ions (anions) gain electrons; positive ions (cations) lose electrons.
- Metals lose electrons, becoming positive ions.
- Non-metals gain electrons, becoming negative ions.
Dot and Cross Diagrams
- Represent electron arrangements in ionic compounds.
- Show electrons as dots and crosses.
- Display ion charges at the top right corner in brackets.
Giant Ionic Lattice
- Regular arrangement of alternating positive and negative ions.
- Strong electrostatic forces hold the lattice together.
- Electrostatic forces act in all directions.
- High melting and boiling points due to these strong forces.
- Solid ionic compounds are called giant ionic lattices.
Representing Ionic Compounds
- 3D ball-and-stick models show ion arrangement, but incorrectly depict bonds and space between ions.
- 3D space-filling models are more accurate, as they show a more densely packed arrangement of ions without gaps.
