Structure And Bonding Flashcards
What type of bonding is in a giant ionic structure?
Ionic (attraction between positive and negative ions)
What is the melting and boiling point like in a giant ionic structure?
Very high or high, because there are very strong forces of attraction in every direction between + and - ions
What is the conductivity like in a giant ionic structure?
Not when solid (ions fixed), when dissolved or molten ions can move and carry charge
What type of model would be used for a giant ionic structure?
Ball and stick
What type of bonding is in a small molecular structure?
Covalent (shared pair of electrons)
What is the melting and boiling point like in a small molecular structure?
Low, because weak intermolecular forced between molecules are easily overcome by small amounts of energy
What is the conductivity like in a small molecular structure?
Neutral with electrons shared so neither atoms or electrons can move and carry charge
What type of model would be used for a small molecular structure?
The weird line thing like O-O or the dot and cross thing
What type of bonding is in a giant metallic structure?
Metallic (attraction between positive metal ion and delocalised electrons)
What is the melting and boiling point like in a giant metallic structure?
High because there are many strong forces of attraction in every direction
What is the conductivity like in a giant metallic structure?
Conduct as solids and liquids due to moving delocalised electrons that can carry the charge through the structure
Which type of structure is malleable?
Giant metallic
Why are giant metallic structures malleable?
Atoms in layers easily slide
What type of model would be used for a giant metallic structure?
The thing with the positively charged circles and a cloud of delocalised electrons
What type of bonding is in a giant covalent structure?
Covalent (shared pair of electrons)
