Question

6) How would you differentiate between a molecule of element and a molecule of compound? Write one example of
each type.​

Answer 1

Answer:

The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. Hydrogen can make only one bond to one other atom.
