Answer to Question #126672 in General Chemistry for Jell

Question

Gallium Arsenide (GaAs) and Gallium Phosphide (GaP) both have zinc blende (ZnS) crystal structure. Which is less dense among these two?

Answer 1

Gallium Arsenide (GaAs) and Gallium Phosphide (GaP) both have zinc blende (ZnS) crystal structure

Both consist of same Crystal structure ,in both Ga atom is common but in one structure P and another As atom size of As atom is greater than P so that is case of GaAs structure void space is more as compare to GaP structure .so that GaP structure is more dense as compare to GaAs structure.
