C2 Flashcards
Bonding that involves attraction between positively charged ions and negatively charged delocalised electrons
Metallic
Which type of bonding involves sharing electrons
Covalent
What structure do Ionic compounds have
A giant lattice structure
What are some uses of Nanoparticles?
Conduct electricity
Used in sin creams protection from UV light
Used to make surgical masks
What can Nanomedicine do?
Fullerenes are absorbed more easily than most particles meaning they could deliver drugs
What is Metallic bonding?
The electrons in their outer shell are delocalised so they can conduct electricity
Strong electrostatic forces between positive metal ions and negative electrons
What are Alloys?
Two or more metals mixed together
Which make them harder
What are polymers?
Large, chain like molecules
What are polymers held together by?
Strong covalent bonds between atoms in molecules
Weak intermolecular forced between molecules
Difference between Alkane and Alkene?
Alkanes have single bonds between carbons
Alkenes have a carbon double bond
Properties of Graphite
Conduct electricity
High melting point
Slippery
Why can Graphite conduct electricity?
Because one electron from each carbon atom is delocalised
Why does Graphite have a high melting point?
Covalent bonds between carbon atoms
Why is graphite slippery?
The layers of carbon atoms and held together by intermolecular forces
What is Diamond?
An allotrope (form) of carbon
