ionic bonding Flashcards
Ionic substances conduct electricity in the liquid state because they contain
many mobile cations and anions.
The brittleness of ionic substances can be best explained by which of the following
Any distortion to the lattice causes repulsion between ions of like charge.
zinc nitrate formula
Zn(NO3)2
magnesium sulfate formula
Mgso4
sodium hydrogen carbonate formula
NaHCO3
which element loses one electron to form a stable ion
sodium
Are usually crystalline solids
The property is due to the close-packed, repeating three-dimensional lattice structure.
Have high melting and boiling points
A large amount of energy is required to separate the ions.
Are brittle, not malleable
An external force causes ions with like charges to align and repel.
Do not conduct electricity in the solid state
The ions are not mobile.
Are often soluble in water
Water molecules disrupt the crystal lattice, allowing free mobile ions to form.
Do conduct electricity in the molten and aqueous states
The ionic lattice has broken down, allowing the ions to move.
Are hard
The property is due to the strength of the ionic bond.
