Answer 2

Explanation: 
Molecules are always more than one atom, and the atoms are chemically bonded together. Molecules can be elements- a set of the same atom (e.g. carbon), or a compound- this consists of different types of atoms chemically bonded together (e.g. water/H2O, containing hydrogen and oxygen).

In a molecule, atoms are bonded together by single, double, or triple bonds. An atom has a nucleus surrounded by electrons. ... So anotherdifference between atoms and molecules is that when similar atomscombine together in varying numbers,molecules of different properties can be formed.

hope this will help u.. :-)
