Ionic |
|
|
None solubility (2 answers) |
Network covalent Metallic |
|
|
High conductivity as a solid |
Metallic (copper wire) |
|
|
No conductivity as a liquid |
Network covalent because it is not soluble |
|
|
Malleable |
Metallic |
|
|
What does it mean that metallic solids have a “sea of electrons” |
Electrons are released into a “sea of electrons”. More electrons, higher attraction with cations. Because the electrons are delocalized they can be hammered around and therefore metallic solids are malleable |
|
|
What bonds can exist in intermolecular solids? |
LD DD H bonds |
|
|
Why do ionic solids shatter? |
When pressure is applied, like charges align and the electrostatic attraction between oppositely charged ions dissapears |
|
|
Why does graphite have good conductivity as a solid? |
It is the exemption of network covalent solids because it has delocalized electrons |
|
|
What solid crumbles? |
Molecular solid |
|
|
In ionic solids do smaller or bigger ions have higher mp |
Smaller ions as electrons are packed tighter therefore more attraction to nucleus |
|
|
What solid dissolves in H2O |
Ionic |
|
|
Solubility if a molecular solid |
Good depending on the solvent |
|
|
Ionic conductivity as a liquid |
High |
