Covalent Bonding and Structures Flashcards
Covalent bonding happens when atoms share what?
Pairs of electrons
Diamond and silicon dioxide have what type of structure?
Giant covalent
Giant covalent structures have what properties?
High MP and BP
Are very strong
Insoluble
Do graphemes and graphite conduct?
Yes
Do silica and diamond conduct?
No
Do simple molecular structures conduct?
No
Simple molecular structures have high MP and BP
True or False?
True
Are simple molecular structures soluble?
No, they are insoluble
Intermolecular structures are _______
Weak
Covalent bonds are _________
Strong
Why do simple molecular structures have low MP and BPs?
It doesn’t take much energy to break intermolecular forces
Why are simple molecular structures not usually not soluble?
There are no charges in the atoms in the structure so they aren’t usually broken up by water molecules
