Describe the structure of the water molecule. Make sure to include the elements, charges, and the bonds that are formed within the molecule itself.
The water molecule contains two hydrogen atoms and one oxygen atom.
The oxygen atom has a partially negative charge and the hydrogen atoms have a slightly positive charge.
The bonds that are formed between the oxygen and hydrogen atoms is called polar-covalent bonds or covalent bonds.
