Bonding Structure And Properties Of Matter Flashcards
(9 cards)
Describe the movement ans arrangement of the subatomic particles in metallic bonding
Positive metal ions surrounded by free electrons
Describe the bonding in ionic compounds
-Metal + non metal ions held together with strong electrostatic forces
-metal=posative ions
-non metal=negative ions
Why can ionic compounds conduct electricity when in a solution
The ions are free to move and conduct electricity
What is a monomer
Made up of only one molecule
What is a polymer
A long chain of monomers
What happens to the intermolecular forces when a liquid turns into a gas
The Forces of attraction between molecules become less as the particles gain energy and move about more
Why can graphite conduct electricity
There are delocalised electrons that can move through the layers
Compare silicon dioxide and diamond
Silicon dioxide contains silicon and oxygen atoms instead of carbon but has a similar structure to diamond
Compare diamond and graphite
-only graphite can conduct
-both forms of carbon
-both form single covalent bonds
-diamond-tetrahedral structure(forms 4 covelant bonds)
Graphite-hexagonal layers(forms 3 covelant bonds)
