Question 13

different forms of the same element that have different properties because of different atom arrangements are called

a)allotropes

b)carbons

c)graphites

d)halogens

Allotropes are the elements has distinct forms of the identical element that have different properties because of different atom arrangements.

Option: A

Explanation:

Allotropy is property of the chemical element which exists in different forms in same physical state, these are called as allotropies. These are dissimilar structural changes of an element. These are bonded jointly in a distinct manner.

Allotrope is used for only chemical elements and are not used for compounds. Consider an element called carbon, the allotropes of carbon are diamond, graphene and fullerenes.
