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.
C - C designates the nominal capacity of the battery. The charge-discharge current is specified in terms of a multiple of C. For example, the 0.1 current for N-1300SC is equal to 1300 X 0.1 = 130mA. C-rate - Unit by which charge and discharge times are scaled.
