Question

Match each scientist with the correct scientific contribution to atomic theory.

a) John Dalton - Electron Cloud Model
b) J.J. Thomson - Plum Pudding Model
c) Niels Bohr - Planetary Model
d) Erwin Schrödinger - Quantum Mechanical Model

Answer 1

The scientists are matched correctly to their contributions as follows: John Dalton with Atomic Theory, J.J. Thomson with Plum Pudding Model, Niels Bohr with Planetary Model, and Erwin Schrödinger with Quantum Mechanical Model.

Step-by-step explanation:

The correct match of each scientist with their contribution to atomic theory is as follows:

• John Dalton - Atomic Theory
• J.J. Thomson - Plum Pudding Model
• Niels Bohr - Planetary Model
• Erwin Schrödinger - Quantum Mechanical Model

John Dalton is best known for postulating his early Atomic Theory, which was a set of principles outlining the nature and behavior of atoms. J.J. Thomson discovered the electron and proposed the Plum Pudding Model of the atom, suggesting that electrons were embedded in a positively charged sphere. Niels Bohr, building on previous models, proposed the Planetary Model, which described electrons orbiting the nucleus in distinct energy levels. Lastly, Erwin Schrödinger contributed significantly to the development of quantum theory and is known for the Quantum Mechanical Model of the atom, which uses complex mathematics to describe the probability of finding electrons in certain areas around the nucleus, known as orbitals.
