Question

Definition of :
. Atom
. conductor
. displacement reaction
. ductility
. elements
. hardness ​

Answer 1

Answer:

Atom:-the smallest part into which an element can be divided

conductor:-a thing like copper that is a good conductor of electricity

displacement reaction:-A single-displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound.

ductility:-Ductility is a measure of a material's ability to undergo significant plastic deformation before rupture or breaking

element:-a smallest particle of element that cannot be further divided

hardness:-Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood).
