CalorieLab's ranking, new for 2015. Full nutrition data unveiled. Read our expose of the diet. Sitting at a desk all day is awful for our health, but a new study finds that just an hour of physical activity daily can mitigate the harmful effects.
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction.n a simplified view of an ionic bond, the bonding electron is not shared at all, but transferred. In this type of bond, the outer atomic orbital of one atom has a vacancy which allows the addition of one or more electrons.
Chemical Bonds. A chemical bond is the electrostatic attraction between two or more atoms strong enough to allow the atoms to act as a single unit. The formation of chemical bonds usually involves the valence electrons; therefore it is very important to know and understand Lewis dot symbols.
