Describe the polarity of Water

• The larger oxygen atom gets a larger share of the electrons and is more negatively charged.

• The smaller hydrogen atoms get a smaller share of the electrons and are more positively charged.

• There is a separation of charge in each water molecule.

• Overall, each water molecule has no net charge.

• All of the above
