3.3 - Ionic Bonding Flashcards
How do metals form ions?
Metal atoms tend to lose all of their outer-shell electrons to get a full outer-shell.
What charge do metal ions have when they lose electron(s)?
they become positively charged ions and they are more stable.
How do non-metals form ions?
Non-metal atoms tend to gain electrons to fill their outer-shell.
What charge do non-metal ions have when they lose electron(s)?
they become negatively charged ions and they are more stable.
What does OILRIG stand for?
Oxidation
Is
Loss
Reduction
Is
Gain
In any ionic compound the charges must be….
equal/balanced.
What is the structure of an ionic compound?
The ions are arranged in a giant ionic lattice
What is ionic bonding?
Ionic bonding is the electrostatic attraction between oppositely charged ions.
Ionic bonding is always a very strong attraction.
Why do ionic compound have high melting points?
- Ionic bonds are very strong
- In a giant ionic lattice there are lots of ionic bonds
- Breaking all the ionic bonds requires a large amount of energy
When can ionic compounds conduct electricity?
When liquid, dissolved or molten. This is because ions can move freely but when it is a solid the ions are ‘stuck’.
