Question

why zinc has lower density than copper​

Answer 1

Answer:

Density is mass/volume. The density of Zn is lower than Cu because of its higher atomic metallic radii than Cu. ... Due to the absence of these unpaired electrons, the inter-atomic electronic bonding is the weakest in Zn and as a result, it has the least enthalpy of atomization.

Answer 2

Answer:

The density of Zn is lower than Cu because of its higher atomic metallic radii than Cu. ... Copper has high atomisation ΔaH° and low hydration energy Δhyd H°.
