N
"The letter ""n"" when used as a prefix before a unit symbol indicates a multiplier of 10-9. Abbreviation of ""nano"". E.g., nV = 10-9 volt, one nanovolt, one billionth of a volt. "
(n) Prefix used in the SI system meaning "multiply by 10-9". For example 1 nm means "0.000000001 m" 2.8 ng could also be written "2.8 × 10-9 g".
(N) Element number 7, a colorless, odorless, tasteless gas that makes up about 80% of the earth's atmosphere.
(N) Compare with molarity and equivalent .A measure of solution concentration, defined as the number of equivalents of solute per liter of solution.
(n) The quantum number that determines the size and (in hydrogen atoms) the energy of an orbital . n is used to label electron shells . n may take on integer values from 1 to infinity.
1. Nano. One billionth. 2. Newtons. Measure of force generally used to specify fiber optic cable strength.
The number of theoretical plates. N = 16(tR/Wb)2, where tR is retention time, and Wb is the base width of the peak. A measure of the efficiency of a column. Sometimes measured as N = 5.54(tR/W 1/2)2 where w1/2 is the peak width at half height.
(N or H). A measure determined by the number of theoretical plates calculated from the equation shown for H (see HETP).
The degree of homogeneity in Euler's equation, interpreted physically as the fall-off rate with distance and geophysically as a structural index (SI). Values vary from 1 to 3 according to magnetic or gravity source body geometry.
