It means that only one atom of the element exist in a single molecule of the compound. For example, Sodium sulfate, Na2SO4 , has 2 sodium atoms, 1 sulfur atom and 4 oxygen atoms. It is supposed to be Na2S1O4, but the former is more commonly used.
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
These subscripts are down the chemical symbol and at right. Example: O2
Right and down the symbol of a chemical element.
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
It use the symbols as alphabetical characters for element names for examples: C for Carbon, Cu for copper (Cuprum in latin)And in the lower left of the symbol is atomic number, for C it is 6: 6Cin the upper left of the symbol is the mass number, for C it is 12 : 12C(or with another isotope, 13)Then the full nomination: 612C (write 6, and 12 one column aligned)(answer)My chemistry book states that its a Chemical Formula, "a shorthand representation of the composition of a substance using atomic symbols and numerical subscripts"
The chemical symbol (not formula) of phosphorous is P; the chemical symbol (not formula) of chlorine is Cl.
The chemical symbol of indium is In.
These coefficients are subscripts after the symbol of the chemical element.
Chemical symbol is code for a chemical element. Chemical formula is way of expressing information.
The chemical formula (not symbol) is NiBr2.
The chemical formula (not symbol) of sodium sulfide is Na2S.
The chemical symbol (not formula) of indium is In.
