Bonding - Coggle Diagram
Bonding
Covalent
Bonding between
non-metals
only
Atoms share electrons to get a full outer shell each
Types of covalent compounds
Giant
Contain many atoms
Held together by
intermolecular
forces
Very high melting and boiling points as they have many strong covalent bonds holding the structure together
Lots of energy needed to
Simple
Don't contain many atoms
Held together by
intermolecular
forces
Generally have low boiling points as they have weak intermolecular forces of attraction
Little energy needed to separate bonds
Ionic
Bonding between a
metal
and a
non-metal
Metals
lose
electrons to become
positive
ions
Non-metals will
gain
electrons to become
negative
ions
Ions are held together by
electrostatic
forces of attraction between positive and negative ions
Properties of Ionic Compounds
Very high melting points
- Electrostatic bonds are very strong so it would take a lot of energy to break
DO NOT conduct electricity when solid
- Ions are in a fixed shape so they can't move around. They are inert
Conduct electricity when molten (liquid) or dissolved (aqueous)
Metallic
Positively charged
metals are bonded to
negatively charged
delocalised electrons
Arranged in regular lattice
Held together by
electrostatic
forces
