Ionic Bonding Flashcards
What happens in ionic bonding?
Atoms lose or gain electrons and turn into ions.
Ionic bonding occurs between which type of elements?
Non-metals and metals.
True or false?
Ions are strongly attracted to each other because of opposite charges?
True.
If an atom loses electrons, does it turn into a positive or negative ion?
Positive. If and atom gains electrons it turns into a negative ion.
What is an ion?
A charged particle.
How are ionic compounds formed?
When ions that have lost or gained electrons to/from each other latch on to one another because of their opposite charges and form an ionic compound.
True or false?
Ionic compounds always have giant ionic lattices.
True.
How are ions arranged in a giant ionic lattice?
They form a closely packed REGULAR LATTICE arrangement.
What type of force is there between oppositely charged ions in ALL directions?
Very strong electrostatic forces of attraction.
Why are salt crystals cuboid?
Because one crystal is one giant ionic lattice, and the ions are held together in a regular lattice arrangement.
Name 3 properties of ionic compounds:
1: high melting/boiling points.
2: conduct electricity.
3: dissolve easily in water.
How do ionic compounds conduct electricity?
When they MELT or DISSOLVE in water, the ions separate and are free to move, so they’ll carry electric current.
