Write the differences between atom and elements.
The difference between atoms and elements are given below:
| Atoms | Elements |
| 1. An atom is the smallest repeating unit that makes up all Matter | 1. Elements comprises of a group of atoms. |
| 2. An atom can have equal or different no. of neutrons and protons present in its nucleus. | 2. Elements have same no. of protons and neutrons. Except in the case of Isotopes, they may have different no. of protons and neutrons. |
| 3. The periodic table shows a series of species of Atoms. | 3. The periodic table shows Known chemical elements (i.e species of atoms). |
| 4. Example: A single chlorine atom has 17 protons in its nucleus. | 4. Example: All the atoms that belong to the element Chlorine has 17 protons in its nuclei. |
