Question

what do we need to revise?think about what we know about bonding, electrons, and outer energy levels. use the space below to draw another possible model of water’s bonds.

Explanation:

The question involves concepts related to chemical bonding and molecular structure. One needs to have knowledge of how atoms bond to form molecules, specifically in the case of water. This includes understanding electron - sharing and the role of outer energy levels in bonding.

Answer:

Draw a model showing the oxygen atom in the center of the water molecule with two single covalent bonds to two hydrogen atoms. The oxygen atom has two lone pairs of electrons on its outer energy level. This represents the typical Lewis - structure model of water's bonds where oxygen shares electrons with hydrogen to complete its outer energy level and hydrogen shares electrons to complete its outer (1s) energy level.
