write two differences between atoms and molecules
Answers
The tiny particle of a chemical element, which may or may not exist independently is called an atom. Molecules refer to the set of the atoms held together by the bond, indicating the smallest unit of a compound. ... Two or more identical or different atoms bonded chemically
Answer:
Difference between Atom nd molecule :-
1) Atom is a smallest particle of an element.
1) Molecule is a group of two or more atoms combined together so it is bigger.
2) Atom consists of nucleus (containing protons and neutrons) and electrons.
2) Molecule consists of combination of two or more like or different atoms chemically bound together e.g. H2, HCl, NaCl etc.
3) Atom can neither be seen through naked eye nor through magnifying microscope.
3) Molecule is not visible to naked eye, while can be seen through highly magnifying microscope.
4) Atom cannot be further divided.
4) Molecule can further be divided to give individual atoms.
5) Atoms may or may not have independent existence.
5) Molecules are capable of having independent existence.For example, atom of oxygen (O) has no independent existence while its molecule exists as O2in nature
6) Atom has nuclear bond or attraction within it i.e. it involves electrostatic attraction between the positive nucleus and electrons.
6) Molecule has chemical attraction or bonding between the atoms i.e. it involves single, double or triple bonds between the atoms.
