Question

Explain with the help of example the difference between an atom and a molecules

Answer 1

Answer:

Explanation:

Definition: Most fundamental and smallest part that can exist of an element. Two or more atoms chemically bonded together.

Example Oxygen – O

Phosphorus – P

Sulphur – S

Hydrogen – H

--------------------------------------------------------------------------------------------------------------

Oxygen – O2

Phosphorus – P4

Sulphur – S8

Water – H2O

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 Elements: 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 a molecule, the level of reactivity is less as some of the valence points are filled by electrons of combined elements.

The First point comes as Atoms and the second Molecules
