"no matter how many atoms are in close to each other" and the error is "are in close". Please look into this.

This may be a grammatical difference between English English and American English.

 

It is either:

no matter how many atoms are in close proximity to each other

Or:

no matter how many atoms are close to each other

Thanks for the work
