Front

What is the Billiard Ball Model?

Back

An early model of the atom proposed by John Dalton, suggesting atoms are solid spheres.

Front

What does the Plum Pudding Model represent?

Back

A model proposed by J.J. Thomson, depicting the atom as a sphere of positive charge with electrons embedded in it.

Front

What is the Nuclear Model of the atom?

Back

A model proposed by Ernest Rutherford, which describes the atom as having a dense nucleus surrounded by electrons.

Front

What is the significance of the Gold Foil Experiment?

Back

Conducted by Rutherford, it led to the discovery of the nucleus and the understanding that atoms are mostly empty space.

Front

What is the main idea of Quantum Mechanics in atomic structure?

Back

It describes the behavior of electrons in atoms as probabilistic rather than deterministic.
