Structure and Properties of Matter Flashcards
What is an allotrope?
A different form of the same element in the same state.
What is a buckyball?
A molecule comprising carbon atoms joined together to form a spherical or nearly spherical hollow structure.
What is a lattice?
A regular grid-like arrangement of atoms in a material.
What is a lubricant?
A substance which reduces the friction between two surfaces.
What is a nanotube?
A long cylindrical molecule made from carbon atoms joined together by covalent bonds.
What are the properties of Diamond?
High MP and BP, Dosen’t conduct electricity, Transparent Crystals, Very Hard
What are the properties of Graphite?
High MP and BP, Conducts Electricity, Grey black solid, Soft and Slippery
What are the properties of Buckminster fullerene?
Low MP and BP, Semiconductor, Yellow Solid , Very light and strong.
What are the properties of graphene?
High MP and BP, Good conductor, transparent sheets, Very strong and flexible.
What are the properties of silicon dioxide?
High MP and BP, Dosen’t conduct electricity, Transparent Crystals, Produces electric charge from mechanical stress.
What is a diamond?
A form (allotrope) of pure carbon in which all the atoms are bonded to four others in a giant tetrahedral network structure
What is a fullerene?
Molecules of carbon with hollow shapes. Their structures are based on hexagonal rings of carbon atoms.
What is Graphite?
A form of pure carbon in which all the atoms are bonded to three others in giant sheets which can slide over each other.
