Mar 15, 2017

There are two types of carbon in terms of stable isotopes

There are three forms of carbon on basis of allotropy.

#### Explanation:

1) The first (stable) carbon isotope is carbon-12 with a mass number of $12$ units {it has $6$ neutrons}

The second (stable) carbon isotope is carbon-13 with a mass number of $13$ units {it has $7$ neutrons}.

2) There are three allotropes of carbon

1. Graphite
2. Diamond
3. Buckminster fullerene
