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.
Answers
The correct answer is options c and e.
A solid solution is basically a multi-component framework that comprises a mixture of two or more elements exhibiting a similar crystal lattice. The examples of solid solutions are alloys.
The requirements for one kind of atom to substitute for another in a solid solution are:
1. The size of the atom must be similar.
2. The substituting atom must be from a similar group.
Answer:
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.

Answer:
Explanation:
As the bacteria are capable of surviving in the hot temperatures as thermophiles they can speed up their respiration rate and hence, will produce more carbon dioxide and potentially accelerating the climate change within a region. The other prokaryotes can also become the significant contributors of the carbon output and these are those which are highly sensitive to the temperature. Methane oxidizing bacteria are also responsible for the contribution in carbon and nitrogen cycles. These bacteria converts the important greenhouse gas methane into carbon and nitrogen compounds like CO2 and NO2 − respectively. Thus methane can be considered as precursor of the temperature rise.

B. Two chlorine atoms
Explanation:
This electronic configuration shows that the given atom is magnesium.
Electronic configuration of magnesium:
Mg¹² = 1s² 2s² 2p⁶ 3s²
There are two valance electrons of magnesium that's why it would react with two atoms of chlorine. Chlorine is present in seventeen group. It has seven valance electrons. It required just one electron to get complete octet. While magnesium needed to lose two electrons to get complete octet. That's why two chlorine atoms bonded with one magnesium atom. Thus both would get complete octet.
Mg + Cl₂ → MgCl₂
