Ionic bonding Flashcards
What kind of substances does ionic compounds contain?
Ionic compounds are combination of metal and non-metal.
Ionic compounds usually contain metals.
True
What are the charged particles call?
Ions
What are the names of positive ion and negative ion?
Positive ion - Cation
Negative ion - Anion
What happen when an ionic compound is formed?
Electrons are transferred from the metal atom to a non-metal atom to form positive and negative ions.
What is ionic bonding?
Ionic bonding is the strong electrostatic attraction between positive and negative ions.
What do ionic compounds form?
Ionic compounds form crystals that consist of lattices of positive and negative ions packed together in a regular way.
What is lattice and what is it hold by.
Lattice is a regular array of particles and it is held together by the strong electrostatic attractions between positively and negatively charged ions.
There are individual molecules in giant ionic lattice?
False
How many particles present in the giant ionic lattice in maximum or minimum?
The particles present are limitless.
What are physical properties of ionic substances?
- Ionic compounds have high melting and boiling point.
- Ionic compounds tend to be crystalline
- Ionic crystals tend to be brittle
- Ionic substances tend to be soluble in water
- Ionic compounds tend to be insoluble in organic solvent
Why ionic compounds have high boiling and melting point?
Because of the strong electrostatic forces of attraction holding the lattice together.
Why even a small distortion of a crystal splits itself apart?
Small distortion of crystal will bring ions with the same charge alongside each other causing them to repel and split apart.
Do ionic compounds conduct electricity and why?
Ionic compounds don’t conduct electricity when they are solid since ions are in fixed positions and are not free to move around.
However, they can conduct electricity when they are molten since ions then become free to move around.
