Covalent bonding is like a tug-of-war. Two atoms share their electrons, but each atom pulls those shared electrons towards itself. When the two atoms pull equally, it is called a nonpolar covalent bond. Atoms form bonds in order to achieve a stable, full outer energy level.For most atoms this means having eight electrons in the outer energy level, like the noble gases.ovalent bonding is like a tug-of-war.

One of the most typical causes of basement flooding is that the house has been constructed on an unsuitable site. Houses are usually built on sloped terrains, allowing accumulated water to drain. If your home has been built on the low part of your estate, chances are it will flooded frequently.
There are a number of reasons why basements flood. Flooding can occur by seepage or flow through the walls or foundation floor, from surface water sources, or by a sanitary or storm sewer backup.Please remember: Basements are inherently prone to flooding.They are, by definition, the lowest level of a building, typically built partly or entirely below ground level. Groundwater is water that is naturally located below the groundâs surface. The groundwater level can be, at times, above the level of the basement floor.looding can occur by seepage or flow through the walls or foundation floor, from surface water sources, or by a sanitary or storm sewer backup.
