Hydrogen Molecule. The classic case of covalent bonding, the hydrogen molecule forms by the overlap of the wavefunctions of the electrons of the respective hydrogen atoms in an interaction which is characterized as an exchange interaction.he potential energy of the anti-bonding orbital shown gives some insight into why a third hydrogen atom cannot bond to the two atoms of the hydrogen molecule. It would be in an anti-bonding situation with one of the other hydrogen atoms and would therefore be repelled.
Depending on the rest of your daily intake you may not even need to drink any extra water in the first place. As a 13 year old your total water intake should be in the region of 1.5 litres per day rising to 2 litres when you become adult.
These numbers include water from food (about 20% of total water intake) and beverages (about 80%). The common recommendation of 8 glasses of 8 ounces of water per day is simple and provides a good starting point for most people, though there is no scientific evidence behind this guideline.
