Answer
The type of bond that exists in a water molecule is a covalent bond
Explanation:
The chosen molecule is water
A covalent bond involves the sharing of electrons between two constituent elements
Looking at the molecular formula of water (H20)
Water = 2 atoms of hydrogen and 1 atom of oxygen
The diagram above shows that there is a sharing of electrons between the hydrogen atom and oxygen atom. The oxygen atom needs two electrons to complete its octet configuration.
Hence, the bond that exist in water molecule is a covalent bond
