Giant Convalent Structures Flashcards
1
Q
Why is graphite hard
A
Because the atoms are held together by strong covalent bonds
2
Q
Why does diamond have a very high boiling point
A
Because the carbon atoms are held together by strong covalent bonds
3
Q
Why is graphite very hard
A
The c atoms are held together by strong covalent bonds
4
Q
Why can graphite conduct electricity
A
The free electrons can move
5
Q
Why does graphite have a very high melting point point
A
The c atoms are together by strong covalent bonds
6
Q
Why is graphite weak soft and brittle
A
Because the layers of c atoms can slide over each other because there are weak forces of attraction between the layers
7
Q
Why won’t diamond conduct electricity
A
No free electrons in the outer shell
