Question

two of the covalent bonds are labeled with blank spaces. drag and drop the electrons to the correct position in both bonds.

Explanation:

Step1: Recall covalent - bond electron sharing

In a water ($H_2O$) molecule, each covalent bond between hydrogen ($H$) and oxygen ($O$) is a single bond. A single covalent bond consists of 2 electrons, which are shared between the two atoms.

Step2: Place electrons in bonds

For each of the $H - O$ covalent bonds in the $H_2O$ molecule, place one electron from the hydrogen atom and one electron from the oxygen atom in the bond - region.

Answer:

Place one electron from $H$ and one electron from $O$ in each of the blank - space covalent bonds.
