is it possible to have opposite for everything ,if so what is opposite of atom
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
A physical change doesn't modify the structure of a substance (the chemical formula).
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.
Lactic acid is a pure substance because it is a compound with a specific chemical formula, C3H6O3, and a specific molecular structure. It is not made up of different substances mixed together.
Caffeine is a compound and so is a pure substance.
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.
A substance can be described using its chemical formula, which consists of the chemical symbols for the elements in that substance and the corresponding numbers to indicate the ratio of each element present in the compound. For example, the chemical formula for water is H2O, showing that it is composed of two hydrogen atoms and one oxygen atom.

Peyote is a plant not a chemical substance.
The identity of a substance refers to its unique characteristics that distinguish it from other substances. This includes its chemical composition, physical properties, and behavior under various conditions. Identifying a substance involves analyzing these properties to determine what it is.
Electricity is not a substance with a specific chemical formula or structural formula. It is the flow of electrons through a conductor like a wire. The behavior of electricity is governed by the movement of electric charge.
