Not quite sure what you mean.
You could mean isomerism, which is changing the structure of molecules (usually hydrocarbons).
You could also be referring to allotropes, which are different forms of the same element. For example, diamond and buckminsterfullerene are both allotropes of carbon.
Two different molecules with the same formula are known as isomers of each other.
Isomers
The chemical formula of glucuronic acid is C6H10O7. However, glucuronolactone is the cyclic ester form of glucuronic acid, so the chemical formula of glucuronolactone is the same as glucuronic acid, C6H10O7.
If they're isomers, they by definition have the same molecular formula.
copper sulfate
C3H8 is the chemical formula of propane (hydrocarbon, alkane).
Isomers are chemical compounds which have the same chemical formula while having different chemical structures. AlH3 does not have compounds with different chemical structure. Therefor AlH3 is not an isomer.Isomers are chemical compounds which have the same chemical formula while having different chemical structures. AlH3 does not have compounds with different chemical structure. Therefor AlH3 is not an isomer.
Isomers have equal chemical formula while having different chemical structures. CH3NH2 does not have different chemical structures with the same chemical formula. Therefor CH3NH2 is not an isomer.

is it possible to have opposite for everything ,if so what is opposite of atom
Chiral isotopes.
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
The chemical formula is the same - NaCl.
the chemical formula for magnesium - Mg and the same for oxygen is - O2
Isomers are pairs of molecules that share the same chemical formula but have different structural arrangements. For example, glucose and fructose both have the chemical formula C6H12O6, but they have different structural arrangements.
Elements have the same chemical formula because they are made up of only one type of atom. For example, the chemical formula for gold is always Au, regardless of its form.
The Chemical formula of Urea is CO(NH2)2 its empirical formula is just the same as its chemical formula. Urea has a molecular weight of 60.06gm.
The chemical formula for Amyl cinnamal, which I am pretty positive is the same substance as Hexyl cinnamal is C15H20O.
