In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

The sucrose molecules dissolve as they are separated from the other molecules and mix into the water. The sucrose molecule has many oxygen-hydrogen (O–H) bonds which are polar. The charge-density ...

A molecule is a group of atoms held together by covalent bonds. Covalent compounds do not ... Ionic compounds dissolve in water easily, when they do this their lattice breaks up completely.

In an oxygen (O2) molecule, both atoms have the same electronegativity. The electrons in the covalent bond are shared equally between the two oxygen atoms. The chlorine atom has a higher ...
