Answer:
1. a positive or negative electric charge
2. held tightly by Oxygen
Step-by-step explanation:
1. Water molecules have the tendency to interact with each other and other molecules due to attraction between opposite electrical charges. These are a result of partial charges on positively charged H atoms and negatively charged O atom.
2. Interactions are also possible when other substances are capable of forming bonds with O atoms. This is because O atoms have two lone pairs available.
