Answer 2

Answer:

Ans 1)(c)Crystallography

Ans2)Yes, the atoms in a molecule are always arranged in a regular pattern . If their pattern is changed then the same molecule is impossible to be made. So, even if one single atom is added or if there is a change in the composition ( arrangement of the atoms ) of the molecule we may get another element or compound.
