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 ...

The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. Electricity causes the rearrangement of electrons and ...

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 ...

Covalent bonds are strong bonds ... Ionic compounds dissolve in water easily, when they do this their lattice breaks up completely. Therefore they can conduct as their ions are free to move.

Researchers have proposed using polymer membranes modified with copper, zinc, and chromium metal ions for water purification. These polymers were used for the first time in water purification via ...
