Diamonds and graphite have different properties and different crystal structures.
In diamonds, the carbon atoms are arranged tetrahedrally, whereas carbon atoms are arranged in an infinite array in graphite. Graphite has a lower density than diamonds... Diamonds are the best conductor of heat that we know of... the properties differ greatly
Answer:
The strength of a bond depends on the amount of overlap between the two orbitals of the bonding atoms
Orbitals bond in the directions in which they protrude or point to obtain maximum overlap
Explanation:
The valence bond theory was proposed by Linus Pauling. Compounds are firmed by overlap of atomic orbitals to attain a favourable overlap integral. The better the overlap integral (extent of overlap) the better or stringer the covalent bond.
Orbitals overlap in directions which ensure a maximum overlap of atomic orbitals in the covalent bond.
