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 ...

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.

Most ionic compounds are soluble in water None required ... The molecules are neutral so there are no ions or delocalised electrons to carry charge. Most molecular covalent substances are insoluble in ...
