In chemistry, superscripted plus and minus signs are used to indicate an ion with a positive or negative charge of 1 (e.g., NH). If the charge is greater than 1, a number indicating the charge is written before the sign (as in SO).
Jan 26, 2016 · While (+) and (-) notation corresponds to the optical activity of the substance, whether it rotates the plane of polarized light clockwise (+) or counterclockwise (-). D-L system tells us about the relative configuration of the molecule, compared to the enantiomers of glyceraldehyde as the standard compound.
Jan 10, 2014 · The minus sign in parentheses here indicates the optical rotation, (+) means the molecule rotates linear polarized light clockwise, (-) means it rotates counterclockwise. Typically you would also write exactly which stereoisomer is meant (R or S), which is generally the more useful information.
Feb 7, 2015 · $\ce{Ba^{2+}}$ means that you have a Barium ion with two positive charges. so the 2 counts the positive charges and the + is not the symbol to add something, the + means only a positive charge.
The plus or minus charges indicates the total charge. If there is a minus sign the atom has more electrons than normal and the positive sign indicates that the atom have less electrons than normal.
