Q

what are ionic formulae?

A

empirical formulae

17
Q

empirical formula

A

simplest ratio of ions

18
Q

ionic compounds have low volatility

A
  • lattice structure of strong attractions
  • lots of energy required to overcome attractions
  • very high melting point
19
Q

ionic compounds do not conduct electricity as solids

A
  • no delocalised electrons present
  • all ions in a fixed lattice position
20
Q

molten/aqueous compounds conduct electricity

A

ions are free to move

21
Q

most ionic compounds are soluble in water

A
  • water is polar
  • ions are charged
  • ions can separate from the lattice and are surrounded by water
  • form new attractions
22
Q

ionization

A

electrons transferred between atoms

23
Q

What does an ionic bond form under normal conditions?

A

lattice structure

24
Q

ionic lattice

A

predictable three-dimensional crystalline structure fixed arrangement of ions based on a repeating unit
