Key Differences Between Atom and Molecule
Atom is defined as the smallest unit of an element which may or may not exists independently. ... Atoms comprise of the nucleus (which contains protons and neutrons) and electrons. Conversely, a molecule comprises of two or more, identical or different atoms, combined chemically.
Answer:
Atom is defined as the smallest unit of an element which may or may not exists independently. On the other hand, molecule implies the set of atoms held together by the bond, indicating the smallest unit of a compound.
Atoms may or may not exist in the free state, but molecules exist in the free state.
Atoms comprise of the nucleus (which contains protons and neutrons) and electrons. Conversely, a molecule comprises of two or more, identical or different atoms, combined chemically.
The shape of an atom is spherical whereas the molecules can be linear, angular or rectangular in shape.
Atoms are highly reactive, i.e. they participate in the chemical reaction without additional decomposition into subatomic units. However, this is not applicable to noble gas atoms. On the contrary, molecules are less reactive, as they do not take part in the chemical reaction.
Atoms possess nuclear bond, as it entails electrostatic attraction between the nucleus and electron. In contrast, there exist a chemical bond between atoms of a molecule, such that it encompasses single, double or triple bonds.
