graphite and graphene Flashcards
1
Q
what is the structure of graphite
A
à carbon bonded 3 other carbon atoms
made up of layers that can slide over each other (weak intermolecular forces)
has strong covalent bonds (high melting points)
2
Q
graphene
A
single layer of graphite
3
Q
giant covalent structures
A
joined together by covalent bonds
4
Q
METTALIC BONDING DEFINTION
A
strong electrostatic forces of attraction between delocalised electrons and closely packed positively charged metal ions.
5

order of increasing atomic weight (relative atomic mass) and similar chemical properties
6
Q
modern periodic table
A
order of increasing atomic number (number of protons in an element)
