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.
of the water, the duration of the flood, terrain and soil conditions, and the built environment (e.g., buildings, roads, and bridges). - Flooding can cause fatalities and serious injuries for people who are trapped or swept away by wading in, driving through, or boating across floodwaters.our goal now, before a flood occurs, is to reduce the risk of damage to structures from flooding. This means elevating critical utilities, such as electrical panels, switches, sockets, wiring, appliances, and heating systems, and waterproofing basements.
