Problem

A sample contains metal M, with atomic radius

135\,\text{pm}

, as the host lattice together with

15\,\text{mol}\%

of metal N, with atomic radius

132\,\text{pm}

, and

1\,\text{mol}\%

of atom Q, with atomic radius

68\,\text{pm}

. For each solute element, state the alloying mechanism occurring in the lattice of M and give one reason based on atomic size.
