Select all that apply. the requirements for one type of atom to substitute for another in a solid solution are:
a. all substitutions must be limited to the same element.
b. an atom must be identical in size.
c. an atom must be similar in size.
d. the substituting atom must be from the same period. e) the substituting atom must be from the same group.

An atom must be similar in size.

The substituting atom must be from the same group.

Explanation:

A solid solution is a solid mixture containing a minor component uniformly distributed within the crystal lattice of another component called the major component. Metal alloys are typical examples of a solid solution.

Note that only atoms of similar size can substitute each other in a solid solution. Usually atoms of elements in the same group have atomic sizes that vary within narrow ranges. Hence atoms of elements in the same group have similar atomic sizes and can substitute each other in a solid solution.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

lol for the pointsss
