Effect of Atomic Structure & Chemical
Bonding on Physical Properties
- Molecular
- Formed by nonmetal(s)
- 4. Generally have low melting points
- 3/4. Do not conduct electricity in any state
(pure form or in a solution)
- Polar Covalent Bonds: 3rd Strongest Intramolecular forces
- Intermolecular forces at work: Dipole-dipole attraction, London dispersion forces
(And Hydrogen Bonding if applicable, [ H atom with O, N, or F atom ])
- Intermolecular forces at work: Dipole-dipole attraction, London dispersion forces
(And Hydrogen Bonding if applicable, [ H atom with O, N, or F atom ])
- 4th Nonpolar Covalent Bonds: Weakest Intramolecular forces
- Intermolecular forces at work: London dispersion (weakest
compared to ionic or polar covalent bonds)
- Intermolecular forces at work: London dispersion (weakest
compared to ionic or polar covalent bonds)
- FORCES RANKED(1-5):
- Intramolecular forces:
- Intermolecular forces:
- 3. Hydrogen Bonding
- 4. Dipole-Dipole
- 5. London Dispersion
- 3. Hydrogen Bonding
- 1. Polar Covalent Bond
- 2. Non-polar Covalent Bond
- Intermolecular forces:
- Intramolecular forces:
- Formed by nonmetal(s)
- Ionic
- Formed from a metal + nonmetal
- 2. Conduct electricity in the liquid state but not in the solid state
(form conductive solutions in water)
- 2. High melting point
- 2nd Strongest Intramolecular forces: Ionic Bond
- Formation: Cations to Anions
- Formation: Cations to Anions
- Intermolecular forces at work: electrostatic
(strongest of intermolecular forces)
- FORCES RANKED:
- Intramolecular force:
- Intermolecular force:
- 2. Electrostatic
- 4. London Dispersion
- 3. Ion-dipole
- 2. Electrostatic
- 1. The Ionic Bond
- Intermolecular force:
- Intramolecular force:
- Formed from a metal + nonmetal
- Covalent Network
- Formed by metalloids/carbon
- 1. Extremely high melting point
- 3/4. Nonconductors of electricity
- Covalent bonds in a continuous network. They're the same as a
regular covalent bond, but being in a network gives them strength
- The covalent network is even stronger than the ionic bond
(even though the ionic bond is generally always stronger)
- The covalent network is even stronger than the ionic bond
(even though the ionic bond is generally always stronger)
- FORCES RANKED:
- Intramolecular forces
- 1. Covalent Network Bond
- Intermolecular forces:
- 2. London Dispersion
- 2. London Dispersion
- 1. Covalent Network Bond
- Intramolecular forces
- Formed by metalloids/carbon
- Metallic
- Formed by metal(s)
- 1. Strong electrical and thermal conductivity
- 3. Melting points vary depending on the metal (i.e. tungsten has a high
melting point, mercury has a low melting point)
- 1st Strongest Intramolecular forces: Metallic Bonds from the attraction
between positive metal ions and their surrounding valence electrons
(which enable them to convey electricity easily)
- Basis of formation: Delocalized electrons to metal cations
- Basis of formation: Delocalized electrons to metal cations
- Intermolecular forces at work: electrostatic
- FORCES RANKED:
- Intramolecular forces
- 1. Metallic Bond
- Intermolecular forces:
- 2. Electrostatic
- 3. London Dispersion
- 2. Electrostatic
- 1. Metallic Bond
- Intramolecular forces
- Formed by metal(s)
- Criteria
- Forces (ranked from weakest to strongest)
- Boiling point/melting point, Conductivity (with conditions)
