Reason : Atoms join together just like that to form molecule even they dont have any type of attraction force

Answer 1

Answer:

Smallest particle of an element or a compound which is capable of independent existence is called molecule.A molecule is formed when two or more atoms join together chemically.Molecules of elements like noble gases such as helium,neon etc are made up of one atom only(molecules are capable of independent existence while atoms are not capable of independent existence).Only in these case atoms are capable of independent existence.Noble gases are monoatomic.
