Vedclass · Answer

(C) The correct answer is $C$. $1$. Atoms are the building blocks of matter,forming molecules and ions. $2$. While most atoms are highly reactive and do not exist independently,noble gases (like $He$,$Ne$,$Ar$) exist as independent atoms. Therefore,the statement that 'Atoms are not able to exist independently' is not universally true. $3$. Atoms are electrically neutral because the number of protons equals the number of electrons. $4$. Atoms combine in large numbers to form visible matter.
