CFC’s illustrate that technical advances can be a “double-edged” sword as CFC's were made for the advantages but soon or later it came as a disadvantage for environment.
CFC's was discovered with many advantages such as they are stable, non-corrosive, and replacement of harmful ammonia used in refrigerators and air conditioning systems. But soon it is also discovered that CFC's are destroying the upper atmosphere layer called ozone, which is a very big disadvantage for us.

Atoms of particles are so small that they cannot be divided further by any physical means.
<h3>What are atoms?</h3>
According to John Dalton, atoms are the smallest, indivisible particles of elements.
However, it was later found out that chemically, atoms consist of protons, neutrons, and electrons.
Thus, the indivisibility of atoms that John Dalton was referring to must be that of physical division.
In other words, the particles of atoms are so small that dividing them further using physical means is absolutely impossible.
