The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons. The electrons are attracted to the positively charged nuclei of the atoms. A dipole results when electrons in a covalent bond are not shared evenly between the two atoms.ovalent bonds are formed when two atoms begin sharing electrons.

Low blood pressure, often caused due to dehydration is another cause of faintness and light headed feeling. Episodes of light headedness often trigger in summers or on exposure to high temperatures are linked with dehydration and fall in blood pressure.
Everyone always puts it down to anxiety, but i know the lightheaded/spacey feeling came before the anxiety. The spacey feeling caused the anxiety. I have done alot of research trying to find my answer. Here are some of the possibilities- TMJ, BBPV, inner ear disorder, candida, EBV, lyme disease, poor circulation, dehydration. There are many different viruses or parasites which can cause it, or it could simply be your eyes or allergies to a food or something else. I am trying to eliminate stuff by changing my lifestyle habits.
