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 difference is that the formula does not have the same categories as the chemical compound does
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.
Isomers
is it possible to have opposite for everything ,if so what is opposite of atom
Chiral isotopes.
the chemical formula for magnesium - Mg and the same for oxygen is - O2
The chemical formula is the same - NaCl.
the difference is that the formula does not have the same categories as the chemical compound does
it is same as ammonium sulphate, (NH4)2SO4
They would be called: ISOMERS.(Def; molecules or molecular compounds that are similar in that they have the same molecular formula, however have different arrangements of the atoms)For example; glucose and fructose
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.
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
