Ionic Compounds Flashcards
What is called the structure of the ionic compounds?
Ionic compounds have a structure called a giant ionic lattice.
What does the ion form?
The ions form a closely packed regular lattice arrangement and there are very strong electrostatic forces of attraction between oppositely charged ions, in all directions in the lattice.
What is a table salt?
A single crystal of sodium chloride is one giant ionic lattice. The Na+ and Cl- ions are held in a regular lattice.
Why ionic compounds have high melting points and boiling points.
They all have high melting points and high boiling points due to the many strong bonds between the ions. It takes lots of energy to overcome this attraction.
What happens when the compound are solid?
When they’re solid, the ions are held in place, so the compounds can’t conduct electricity.
What happens when the compounds are melt?
When ionic compounds melt, the ions are free to move and they’ll carry electricity change.
What happens when the compounds are in the water?
Some ionic compounds dissolve in water. The ions separate and are all free to move in the solution, so they’ll carry electric change.
