Question

Differentiate between the following

Atom and molecule

Answer 1

Factor	Atoms	Molecules
Definition	The most fundamental and smallest part are can exist of an element.	Two or more atoms chemically bonded together.
Example	Oxygen –$\mathrm{O}$ Phosphorus – $\mathrm{P}$ Sulfur – $\mathrm{S}$ Hydrogen – $\mathrm{H}$	Oxygen –${\mathrm{O}}_2$ Phosphorus – ${\mathrm{P}}_4$ Sulfur – ${\mathrm{S}}_8$ Water – ${\mathrm{H}}_2\mathrm{O}$
Structure	The smallest particle with properties of an element.	Combination of two or more atoms.
Stability	An atom may not always be stable in nature due to the presence of electrons in the outer shells.	Molecules are formed to attain stability.
Constituent Particles	Protons, Electrons & Neutrons	Two or more atoms of the same or different elements
Reactivity	Except for the noble elements, atoms of all elements showcase a certain level of reactivity.	Compared to an atom, the level of reactivity is less because some valence points are filled by electrons of combined elements.
