Flashcards in Properties and Bonding Overview Deck (12):
1

Ionic melting point

High

  • Many strong forces to overcome before the ions can be freed from their positions in the lattice

2

Ionic volatility

Low

  • Many strong forces to overcome before the ions can be freed from their positions in the lattice

3

Ionic electrical conductivity

Solid state: insulators

  • Have no freely moving charged particles (locked into lattice)

Molten/aqueous state: conductors

  • Charged ions can carry an electric current because free to move.

4

Ionic solubility

  • Can easily form bonds to polar solvent molecules

Soluble in polar solvents

Insoluble in non-polar solvents

5

Covalent melting point

Low

  • Bonds between molecules weak
  • Only requires a small quantity of heat energy to break electrostatic attraction

6

Covalent volatility

Volatile

  • Bonds between molecules weak
  • Only requires a small quantity of heat energy to break electrostatic attraction

7

Covalent electrical conductivity

Not conductive

  • No charged particles

8

Covalent solubility

Non-polar do not dissolve in polar solvents (except water)

Non-polar covalent compounds will dissolve only in non-polar solvents

9

Giant covalent melting point

Extremely high

  • Many strong forces to overcome before the ions can be freed from their positions in the lattice

10

Giant covalent solubility

Low in all solvents

11

Giant covalent volatility

Low

  • Many strong forces to overcome before the ions can be freed from their positions in the lattice

12

Giant covalent electrical conductivity

Depends on the availability of electrons in the valence shell (e.g. graphite)
