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.
In a representative particle of aluminum hydroxide, ( \text{AI(OH)}_3 ), there are three hydroxide groups (OH). Each hydroxide group contains one hydrogen atom, so there are a total of three hydrogen atoms in a representative particle of ( \text{AI(OH)}_3 ).
The number of neutrons is different for each isotope.
