Define Lattice Energy for an ionic solid?
|
The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound.
|
Think Bonds
|
|
|
Which of the following is true about Lattice Energy
a) is equivalent to the amount of energy required to separate a solid ionic compound into gaseous ions. b)Lattice energy is directly related to the distances of ionic bonds c) It is independent of ionic charge and radius d) All of the Above |
The answer is A
Lattice energy is equal to the amount of energy that is needed to separate an ionic compound into gaseous ions. |

What type of bond hold together ionic compounds?
|
Ionic Bonds
|
|
|
|
Which of the following is false of ionic compounds?
a)Ionic compounds are held together by covalent bonds. b)Ionic compounds have high melting and boiling points. c) Ionic Compounds have a high hardness and are brittle to a great extent. D) Solubility is often low in ionic compounds E) Both A and D |
The answer is E:
Ionic Compounds are often very soluble (Salt) and are held together by ionic bonds not covalent ones |
