Question

1. Which atom in the water molecule is positively charged? square 2. Which atom in the water molecule is negatively charged? square 3. What do you notice about the negatively charged atom of one atom in one molecule and the positively charged atom of another water atom when they touch? 4. Describe the movement of the water molecules at cold temperatures.

Answer 1

1. Hydrogen2. Oxygen3. Hydrogen bonds form between the negatively charged oxygen atom of one water molecule and the positively charged hydrogen atom of another water molecule.4. At cold temperatures, water molecules move more slowly and are closer together, often forming a solid structure (ice) due to hydrogen bonding.

Answer 2

1. In a water molecule (H₂O), the hydrogen atoms are slightly positively charged due to the polar covalent bonds with oxygen.2. The oxygen atom in a water molecule is slightly negatively charged because it has a higher electronegativity compared to hydrogen.3. When the negatively charged oxygen atom of one water molecule comes into contact with the positively charged hydrogen atom of another water molecule, hydrogen bonds form.4. At cold temperatures, water molecules move more slowly and are closer together, often forming a solid structure (ice) due to hydrogen bonding.
