Vedclass · Accepted Answer

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) The Assertion is correct because a tetrahedral void is formed by the contact of $4$ spheres,and an octahedral void is formed by the contact of $6$ spheres.The Reason is also correct because the names 'tetrahedral' and 'octahedral' are derived from the geometric arrangement of the spheres surrounding the void.Since the number of surrounding spheres directly determines the geometry of the void,the Reason correctly explains the Assertion.

Assertion : In close packing of spheres,a tetrahedral void is surrounded by four spheres whereas an octahedral void is surrounded by six spheres.
Reason : $A$ tetrahedral void has a tetrahedral shape whereas an octahedral void has an octahedral shape.
