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