Fichas del conjunto (9)
- 1What is Ionic Bonding?Electrostatic force of attraction between oppositely charged ions, forming a valence
- 2What ΔEN characterises ionic bonding?ΔEN > 1.7
- 3What sort of macroscopic structure do ions form?Giant ionic lattice
- 4Describe the melting/boiling points of ionic compoundsMost solid at RTP
Boiling points relatively high
Melting points relatively high - 5Why are mpt/bpt so high?Energy required to overcome strong electrostatic forces between ions
- 6What causes an increase in mpt/bpt?Smaller ions/higher charges
- 7What are ionic compounds soluble in?Polar solvents i.e. water, break the lattice shield the ionic charges
- 8What ionic compounds are relatively insoluble in water and why?Ionic compounds with large charges may have electrostatic attractions that are too high for water to break the lattice
- 9Describe the electrical conductivity of ionic compoundsDon't conduct when solid, ions are fixed in the giant ionic lattice
No mobile charge carriers
When melted or dissolved in water, does conduct.
