Notes:
I. __________________ is the most versatile atom in biological compounds because:
-It can form up to ____________ bonds
- It is found in all ___________________ compounds, in fact it’s presence in a compound defines it as
______________.
-Its flexibility allows it to create molecules of various shapes:
1.______________________
2._______________________
3. ._______________________
II. ______________________ are molecules made of only two elements. ( ______________________ and
