explanations Flashcards
1
Q
explain high MP and BP do
A
alot of energy is needed to break the bonds
2
Q
explain good conductor of electricity do
A
de-localised electrons are free to move and carry charge
3
Q
explain hardness
A
strong bonds so the structufe is strongly held together
4
Q
explain malleable
A
layers of metal ions can slide over each other
5
Q
explain ductile (drawn to wires)
A
layers off metal ions can slide over each other
6
Q
explain very low MP and BP
A
very little energy is needed to break the bonds
7
Q
explain poor conductors
A
there are no charged particles to move and carry the charge
8
Q
explain very strong
A
strong covalent bonds make it a strong material
9
Q
explain soft
A
the weak forces allow the layers allows them to slide over each other
