Respuesta :
The requirements for one type of atom to substitute for another in a solid solution are that "An atom must be similar in size." Although of course there are sometimes exceptions.
Ans: C) and E)
A solid solution is essentially a multicomponent system which is composed of a mixture of two or more elements sharing the same crystal lattice. Alloys are solid solutions.
The requirement for one type of atom to substitute for another in a solid solution are two fold
1) The atom must be similar in size
2) The substituting atom must be from the same group.
