Atomic Theory Scientists -SY24

Front

What is the Plum Pudding Model?

Back

A model of atomic structure proposed by J.J. Thomson, suggesting that atoms consist of a positively charged 'soup' with negatively charged electrons scattered throughout.

Front

Who proposed the Electron Cloud Model?

Back

The Electron Cloud Model was developed based on the work of several scientists, including Erwin Schrödinger, and describes electrons as existing in probabilistic clouds around the nucleus.

Front

What did John Dalton contribute to atomic theory?

Back

John Dalton proposed that atoms are indivisible and that each element consists of identical atoms that differ from those of other elements.

Front

What is the main difference between the Bohr Model and the Electron Cloud Model?

Back

The Bohr Model depicts electrons in fixed orbits around the nucleus, while the Electron Cloud Model describes electrons as existing in probabilistic clouds.

Front

Who is known for the discovery of the nucleus?

Back

Ernest Rutherford is known for discovering the nucleus through his gold foil experiment.

Front

What did J.J. Thomson discover?

Back

J.J. Thomson discovered the electron and proposed the Plum Pudding Model of the atom.

Front

What is the significance of Ernest Rutherford's gold foil experiment?

Back

Rutherford's gold foil experiment demonstrated that atoms have a small, dense, positively charged nucleus.

Front

True or False: John Dalton believed that atoms could be divided into smaller particles.

Back

False. John Dalton believed that atoms were indivisible.

Front

What did Niels Bohr contribute to atomic theory?

Back

Niels Bohr proposed that electrons travel in specific orbits around the nucleus and introduced the idea of quantized energy levels.

Front

What is the main idea of the Atomic Theory?

Back

The Atomic Theory states that matter is composed of small, indivisible particles called atoms, which combine in specific ratios to form compounds.
