If same type of atoms are packed in hexagonal close packing and cubic close packing separately, then

Options

  1. Adensity of hcp will be greater than ccp
  2. Bdensity of hep will be smaller than ccp
  3. Cdensity of hcp will be equal to ccp
  4. Ddensity of hep and ccp will depend upon the temperature of the system

Correct answer

C. density of hcp will be equal to ccp

Step-by-step solution

Hexagonal close packing and cubic close packing are equally efficient. Density of both the packings will be same.
