Question
If the watermelon defines the atom, what does the seeds in the watermelon defines?
- Electron
- Proton
- Neutron
- Isotope
Hint:
The seeds will be considered as protons if the watermelon is electrons.
The correct answer is: Proton
- The watermelon model was proposed by J J Thomson.
- He explained that the atom has tiny negatively charged electrons embedded with positively charged particles.
- If the watermelon is positively charged electrons, the seeds of the watermelon will be positively charged protons.
