C2- Ionic bonding, properties, Covalent Bonding, Giant Covalent Bonding and Metallic Bonding Flashcards
When are ions made?
When electrons are transferred
What are ions?
Charged particles
Do metals form positive or negative ions?
Positive as they lose electrons
Do non-metals form positive or negative ions?
Negative as they gain electrons
Ionic Bonding is the….of electrons
Transfer
What type of structure do ionic compounds have?
A regular lattice structure/ giant ionic lattice
Properties of an Ionic Compound?
- high melting points
- high boiling points
- cannot conduct electricity when solid
- some ionic compounds dissolve easily in water
Covalent Bonding is the…..of electrons
sharing
Covalent Bonding occurs between two…
non-metals
Ionic Bonding occurs between…..
A metal and a non-metal
What are polymers?
long chains of repeating units
Give examples of giant covalent structures.
Diamond
Graphite
Silicon dioxide
What is metallic bonding?
Involves delocalised electrons
What is an alloy?
Mixture of two or more metals. Alloys are harder than pure metal
Name the three states of matter
Solid, liquid and gas
