Carbon's atomic number is 6, which means it has 6 protons.
-
It's what's known as a polymorph,
-
meaning it can exist in more than one form, or crystal structure.
-
Each form is called an allotrope.
-
The best example for Carbon
-
is graphite
-
and diamond.
-
Allotropes occur when the atoms bond together in different ways.
-
Watch to see the difference between
-
a graphite and diamond structure.
-
The bond for graphite atoms are weak
-
making it easy to break.
-
But diamonds are bonded together strongly.
