-To be able to understand better the covalent bonds formed in a water molecule.

Hypothesis
I think that in this lab practice we will be able to understand better theterm of covalent bonding by a constructing a water molecule.

Theoretical frame

A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs ofelectrons between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.
