How does the size of oxygens nucleus affect the distribution of electrons in the water molecule

The oxygen atom's nucleus is composed of eight neutrons and eight protons. The protons that are present have a positive charge, which attracts the electrons within the water molecule and pulls them closer.
This way, the negative charge of the water molecule is concentrated around the oxygen atom, creating a partial negative charge. Meanwhile, the hydrogen atoms are left with a partial positive charge as electrons have moved away from them.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
