IPA: /ˌæl.əˈtrɒp.ɪk/
KK: /əˈlɒtrəpɪk/
Referring to a type of substance that can exist in different forms or structures, especially in the case of elements that can have multiple physical forms.
Carbon can exist in an allotropic form as both diamond and graphite.
Allotropic → It is formed from "allo-" (from Greek "allos", meaning other or different) and "tropē" (from Greek "tropos", meaning turn or change). The word "allotropic" refers to different forms or structures of the same element, indicating a change in arrangement or form.
Think of 'other' ('allo-') forms or 'changes' ('tropē') of an element — that's what allotropic means.
