Parts and what they mean
- Uniform positive charge (Thomson) (समान रूप से फैला धनावेश (टॉमसन)) — In Thomson’s model the positive charge fills the whole atom uniformly, like the pudding.
- Electrons embedded (Thomson) (धँसे हुए इलेक्ट्रॉन (टॉमसन)) — Electrons sit inside the positive sphere like seeds in a watermelon.
- Nucleus (Rutherford) (नाभिक (रदरफ़ोर्ड)) — All the positive charge and almost all the mass, packed in a size of about 10⁻¹⁵–10⁻¹⁴ m.
- Electrons in orbits (Rutherford) (कक्षाओं में इलेक्ट्रॉन (रदरफ़ोर्ड)) — Electrons revolve around the nucleus like planets around the sun.
- Orbits (कक्षाएँ) — Paths of the revolving electrons (classical picture).
- Empty space (रिक्त स्थान) — Atom size ~10⁻¹⁰ m but nucleus ~10⁻¹⁵ m: almost the whole atom is empty, so most α-particles pass straight through.
