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.
Clean the rain gutters in the spring and after all the leaves have come down in the fall. Blocked gutters will cause all of the roof water to dump directly against your foundation, increasing the likelihood of basement flooding. 3. Extend the rain gutter downspouts well out and away from your home. Do not connect the downspouts to your foundation footer drain tiles or to underground dry wells. This will only cause the roof water to further saturate the ground and cause flooding in your basement. 4. Walk around outside in your yard during a heavy rainstorm.
