The representative particle for iodine is the iodine atom (I).
When an iodine-131 atom decays by emitting a beta particle and a gamma particle, it forms xenon-131. The beta particle is an electron, while the gamma particle is a high-energy photon. This decay process helps iodine-131 become a stable element, xenon-131.
A molecule, SO2
atom
If you think to formula unit this is Na2S.
Iodine-131 decays through beta decay by emitting a beta particle and a gamma ray. This process transforms a neutron in the iodine-131 nucleus into a proton, resulting in the formation of xenon-131.

A molecule is the representative particle of a molecular compound. Molecules don't have representative particles, they are one.

The representative particle of a sodium ion is Na⁺, which has lost one electron to become positively charged.

A water molecule (H2O) contain two hydrogen atoms.
The term for the simplest representative particle in a compound composed of nonmetal atoms is a molecule. A molecule consists of two or more nonmetal atoms chemically bonded together.
The smallest representative particle for a compound like H2O (water) is a molecule, which consists of two hydrogen atoms bonded to one oxygen atom.
If you think to formula unit this is Na2S.
The number of neutrons is different for each isotope.
The representative particle in plutonium is an atom. Plutonium is a chemical element with the atomic number 94, and each atom of plutonium contains 94 protons in its nucleus.
