A subscript looks like this Subscripts are numbers used to tell you how many atoms of an element are present in the equation; for instance: * water H20 has 2 atoms of hydrogen and one of oxygen * glucose C6H12O6 has 6 atoms of carbon, 12 of hydrogen, and 6 of oxygen The large numbers put in front of an equation, either to balance it, or simply to tell you how many molecules there are, is called a coefficient; e.g. in 2H2O , the first '2' is the coefficient, & means that all the atoms following it have to be multiplied by that number - so in 2H2O there are 4 atoms of H, and 2 atoms of 0
The subscript near to an element chemical symbol has the significance of number of atoms of this element in the molecule.
The subscript is equal to the number of atoms from a given element, in the chemical formula.
The meaning is the number of atoms for a given element in the chemical formula
Example: sodium carbonate, Na2CO3
This molecule contain 2 sodium atoms, 3 oxygen atoms, 1 carbon atom.
It is the number of atoms in the preceding element.
reaction
it stands for aqueous, meaning it is able to dissolve in water.
The meaning is that only one atom exists.
This number is the number of atoms of this element in the formula; and subscript meaning is down.
Either a single atom of the element, if there is no subscript number in the formula, or the number of atoms of the element commonly joined to each other in a polyatomic but mono-elemental molecule of the element if the formula does include a subscript number.
reaction
The meaning of this subscript is the base of a specific logarithm; example: log10, the usual logarithm with the base 10.
Your question is a little vague however, you may be referring to 'superscript' and 'subscript' numbers - as you would find in mathematics or chemistry. See the following examples... Mathematics - 3.1415 x 106 - meaning the short form of 3,141,500 or Chemistry H2SO4 - the chemical formula for Sulphuric acid.
The meaning is that only one atom exists.
it stands for aqueous, meaning it is able to dissolve in water.
This number is the number of atoms of this element in the formula; and subscript meaning is down.
Either a single atom of the element, if there is no subscript number in the formula, or the number of atoms of the element commonly joined to each other in a polyatomic but mono-elemental molecule of the element if the formula does include a subscript number.
A symbol with no subscript has an implicit subscript of 1, meaning one atom of that element per formula unit. I'm not quite sure that's what you were asking.
Reduction in chemistry has the meaning of gain of electrons.
VD in chemistry goes to Vapor Density
The meaning in chemistry is identical to the meaning in statistics; weiggted averaging is useful in the processing of experimental data.
Inorganic chemistry is the chemistry of compounds that don't contain the hydrocarbon radicals.
