An atom of an element has no electron. Will that atom have any mass or not? Can an atom exist without electron? If so then give example.

उत्तर
- Atoms with no electron will have mass, because mass depends on number of Protons and Neutrons though it has no electron.
- Atoms can exist without electrons, Matter is build out of neutrons, protons (+) and electrons (-). Matter becomes stable only if it is electrically neutral.
- So atoms without electrons do exist and must have their own states (charged or uncharged transfered back and forth in their environment)
- Example: He2+. It has 2 protons and 2 neutrons but no electrons.

To have an idea of what atoms are, students can be asked to construct atoms using pipe cleaners (thin metal wires-electron shells), pompoms (balls-different colours for protons and neutrons) and beads (electrons). Students will love and enjoy putting them together and they look great hanging from the ceiling in the classroom.
