Answer:
I think its B "The inability of atoms to align perfectly with other atoms"
Step-by-step explanation:
I tried the other persons answer, C, and it was the only question I got wrong. I checked the lesson, and it says:
"With so many combinations possible, it seems as if the number of compounds in the world is infinite. Unfortunately, the number of compounds possible is limited by three main factors.
1
There are a limited number of elements available on the periodic table to use in compounds.
2
Some elements are less reactive than others or do not react at all.
Example: some of the transition metals or noble gases.
3
Many elements are unable to react with other elements because their atoms cannot align.
Example: lithium and sodium do not react with each other."
Point #3 has our answer.
DO NOT USE THE OTHER PERSONS ANSWER, ITS WRONG.
