Explanation:
Atoms are the species which cannot be divided into its constituent particles. These atoms when joined together then they tend to constitute a molecule.
For example, a piece of gold is made up of number of gold atoms.
So, when we cut this gold piece into smaller pieces then its atoms also get separated from each other. But when we separate the gold into tiny pieces that could no longer be divided without losing their gold-like properties then it means that now each of its atoms has been separated out that cannot be divided further.
Thus, we can conclude that you have a piece of gold and you cut it into smaller pieces. If you could continue cutting, you would eventually separate the gold into tiny pieces that could no longer be divided without losing their gold-like properties. These individual component pieces are called atoms.
