Question

The smallest particle of iron oxide is a molecule.why?

Answer 1

Answer:

Actually smallest unit of a compound is molecule. Molecule is formed of two or more atoms. But molecule as a whole is a single entity.

Whereas a metal or an element is usually identified by a smallest unit or entity called an atom.

In one mole of a compound there are always 6*1023 atoms or molecules .

Answer 2

The smallest particle of iron oxide is a molecule because iron oxide is a compound.

- In a compound, the smallest unit is its molecule.

- A single molecule of Iron oxide shows the characteristics of the iron oxide.

- If we divide a single molecule of Iron oxide, it will split into its constituent atoms Fe and O.

- It will not remain iron oxide anymore.

- Moreover, it will lose its characteristics.

- Hence, the smallest particle of iron oxide is a molecule and not an atom.
