Atomic Theory and Structure Concepts

Front

What does Schrodinger's model of the atom propose about electrons?

Back

Electrons move in clouds around the nucleus, rather than in fixed orbits.

Front

What was the conclusion of Rutherford's Gold Foil experiment?

Back

Gold atoms have a solid nucleus.

Front

Who described the atom as having a positively charged nucleus surrounded by empty space?

Back

Ernest Rutherford.

Front

What is a key feature of Rutherford's atomic model?

Back

It includes a nucleus at the center of the atom.

Front

What is a limitation of Bohr's model of the atom?

Back

He did not know how large atoms stopped electrons from slamming into the nucleus.

Front

What is the nucleus of an atom composed of?

Back

Protons and neutrons.

Front

What did Thomson's model of the atom propose?

Back

Atoms are composed of electrons scattered within a positively charged 'soup'.

Front

What is the significance of the Gold Foil experiment in atomic theory?

Back

It led to the discovery of the atomic nucleus.

Front

What is the main difference between Bohr's model and Schrodinger's model?

Back

Bohr's model has electrons in fixed orbits, while Schrodinger's model has electrons in probabilistic clouds.

Front

What is the charge of a proton?

Back

Positive.
