Best Answer

If they are in different physical form they are ALLOTROPES.

If they are in different atomic form they are ISOTOPES.

e.g.

Allotropes [

Graphite, diamond and buckyballs* buckminster Fullerene) are allotropes of carbon. They appear different because the arrangment of the atomis is different.

Isotopes

Carbon 12 , Carbon-13, Carbon-14 are isotopes of carbon , because they have a different number of neutrons in the nucleus.
