Chapter 12.3, Problem 2PE

Interpretation Introduction

Interpretation: The validation regarding the formation of a substitutional alloy when Gold with atomic radius $144\text{pm}$ combines with silver atom (atomic radius $144\text{pm}$) or with copper atom (atomic radius $128\text{pm}$) is to be stated.

Concept introduction: A mixture of metals that has many metallic properties different from those of its constitute elements is termed as an alloy. Alloy can be formed by substituting one metal atom for another of similar size in the lattice is called as substitutional alloy.

To determine: The validation regarding the formation of a substitutional alloy when Gold with atomic radius $144\text{pm}$ combines with silver atom (atomic radius $144\text{pm}$) or with copper atom (atomic radius $128\text{pm}$).
