Question

state the true or false. Elements having same physical properties and different chemical properties are called allotropes.​

Answer 1

Answer:

Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other', and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements. ... The term allotropy is used for elements only, not for compounds.

so this statement is true.
