name 5 scientific models that explain the structure of the atom
Answer (1)
Here's a brief description of each:1. Solid Sphere Model (Dalton's Model):This model, proposed by John Dalton, envisioned the atom as a solid, indivisible sphere, like a billiard ball. 2. Plum Pudding Model (Thomson's Model):J.J. Thomson proposed that atoms are composed of electrons embedded in a positively charged sphere, much like plums in a pudding. 3. Nuclear Model (Rutherford's Model):Ernest Rutherford's model depicted the atom as having a small, dense, positively charged nucleus at the center, with electrons orbiting around it. 4. Planetary Model (Bohr's Model):Niels Bohr's model refined Rutherford's by suggesting that electrons orbit the nucleus in specific, quantized energy levels or shells. 5. Quantum Mechanical Model:This model, developed later, describes the atom as a cloud of electrons surrounding the nucleus, where the probability of finding an electron in a specific region is determined by quantum mechanics.
