A) structural arrangements
B) atomic masses
C) atomic numbers
D) electronegativities

Answer 1

structural arrangements

_______________________________________

properties of daimond:

appearance: transparent

hardness: very hard

thermal conductivity :very poor

electric conductivity: poor

density:

`3510 {kgm}^(3)`

uses: jewellery and drilling

properties of graphite:

appearance: black shiny

hardness: soft ,slippery to touch

thermal conductivity : moderate

electric conductivity: good

density:

`2250 {kgm}^(3)`

uses:dry cell, electric arc, pencil lead, lubricant

How Diamond and Graphite are chemically identical?

• On heating diamond or graphite in the air, they burn completely to form carbon dioxide.
• - Equal quantities of diamond and graphite when burned, produce exactly the same amount of carbon dioxide.

Why the physical properties of diamond and graphite are so different?

Due to the difference in the arrangement of carbon atoms in diamond and graphite
