Question

1. 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?

Explanation:

When the negatively - charged atom of one water molecule and the positively - charged atom of another water molecule touch, they form a hydrogen bond. This occurs because water is a polar molecule with a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. The attraction between these opposite partial charges leads to hydrogen - bonding.

Answer:

They form a hydrogen bond due to the attraction between opposite partial charges.
