As in other autoimmune diseases such as lupus and rheumatoid arthritis, the bodyâs natural ability to attack invading viruses and bacteria goes haywire and mistakenly sees healthy body proteins as enemies. Redness, pain, heat and swelling signal that the immune system is on the warpath.
Formal Charge = [# valence electrons on neutral atom] â [(# lone electron pairs) + (Â½ # bonding electrons)] 1  Valence electrons = corresponds to the group number of the periodic table (for representative elements).  Lone Pairs = lone electrons sitting on the atom. Each electron counts as one and so a pair counts as two.
Electric charge is a physical property of matter that causes it to experience a force when near other electrically charged matter. Electric Charge (symbol q) is measured in SI units called Coulombs, which are abbreviated with the letter capital C. We know that q=n*e, where n = number of electrons and e= 1.6*10-19.
