[Borek]

What are your thoughts?

Start with the definition.

 

[mimi88]

I think it is C?? They look like sharing a different arrangement but same formula ??

 

[Borek]

OK

Extra question: and how would you call forms listed in point A? D?

 

[mimi88]

Ah...A is constitutional isomers?? And D is three-dimensional lattice??

 

[Borek]

Nope, take a step back and forget about isomers.

What do you call two different atoms with same number of protons but different numbers of neutrons?

When an element can exist is different forms, how do you call them?

 

[mimi88]

I this they are isotopes . Do you mean Allot-ropes for that element?

 

[Borek]

Yes.
