1. A bond in which two atoms share electrons but there is an unequal attraction for the shared electrons is a(n). Ionic bond Polar covalent bond Nonpolar covalent bond Hydrogen bond. 2. A hydrogen bond is a.
The bond within a water molecule is a polar covalent bond.
A hydrogen bond is an attraction between two different water molecules (or other polar molecules). This attraction occurs because the polar covalent bond creates charged poles in each molecule (oxygen end is negatively charged and hydrogen pole is positively charged.) The oxygen end of one molecule is attracted to a hydrogen end of another.
3. Water molecules stick together, creating surface tension, due to the attraction between opposite poles of water molecules forming hydrogen bonds. This ability to stick together means that water is _______.
Cohesion = the attraction between like molecules
Adhesion = the attraction between different types of molecules
Water is both cohesive (between water molecules) and adhesive with many molecules..
Since water is a polar molecule, it attracts both ionic compounds (since charged ions are attracted to the partially charge poles of the water molecule) and other polar compounds (since the oppositely charged poles are attracted to water’s charged poles.)
