Models of the Atoms Practice

Front

Where did Rutherford's model state the electrons were located?

Back

Electron Cloud (space around the nucleus)

Front

According to Bohr's model, what must electrons gain to jump from one energy level to another?

Back

Energy

Front

Where is all the positive charge and most of the mass of an atom located according to Rutherford?

Back

Nucleus

Front

In Bohr's model, what is the relationship between energy levels and electron orbits?

Back

Higher energy levels are further from the nucleus.

Front

What is the main feature of the Quantum Mechanical Model of the atom?

Back

Electrons are found in probabilistic orbitals rather than fixed orbits.

Front

What does the term 'nucleus' refer to in atomic structure?

Back

The central part of an atom containing protons and neutrons.

Front

What is the significance of energy levels in Bohr's model?

Back

They represent the fixed distances from the nucleus where electrons can exist.

Front

How does the Quantum Mechanical Model differ from Bohr's model?

Back

It incorporates wave-particle duality and does not define exact paths for electrons.

Front

What is an electron cloud?

Back

A region around the nucleus where electrons are likely to be found.

Front

What is the charge of a proton?

Back

Positive.
