15 Questions
What type of elements typically form Ionic Compounds?
Metals and nonmetals
What is the role of metals in the formation of Ionic Compounds?
They make up the cation, or positively charged portion
What happens to the electron configuration of a metal when it forms a cation in an ionic bond?
It loses electrons from its outermost energy level
What is the result of a metal transferring an electron to a nonmetal in the formation of an ionic bond?
Formation of a cation and an anion
In addition to metals and nonmetals, what else can form ionic compounds?
Charged polyatomic ions
What is the main reason for the high melting and boiling points of ionic compounds?
Strong intermolecular forces between the ionic charges
Why do solid ionic compounds not conduct electricity?
The ions are not mobile in the crystal lattice
What is the term used to describe the energy released when oppositely charged ions form a solid crystal lattice?
Lattice energy
Why are ionic compounds good conductors when dissolved in water?
The constituent ions separate and become mobile in the solution
What is the term used to describe the rigid, very ordered structure resulting from the strong ionic bond in an ionic compound?
Crystal lattice
What is the result of the ionic bond formation between sodium and chlorine?
Sodium becomes a positively charged cation and chlorine becomes a negatively charged anion
What is the role of lattice energy in solid ionic compounds?
Lattice energy is released when ions form a crystal lattice, holding the compound together
Why do solid ionic compounds typically have high melting and boiling points?
Due to the strong intermolecular forces between the ionic charges
What happens when a solid ionic compound is placed into a flask of water?
The water dissolves the ionic compound, forming an aqueous solution
Why are dry solid ionic compounds good insulators?
They do not conduct electricity in their solid state
