Atomic Structure and Quantum Mechanics Quiz

What is the principle behind Rutherford's model of the atom?

• Electrons orbit the nucleus in fixed paths.

• Electrons are embedded in a positive sphere.

• Electrons surround a nucleus.

• Electrons are scattered throughout the atom.

According to Bohr's model, what happens when an electron moves to a higher energy orbit?

• It emits light.

• It absorbs light.

• It loses energy.

• It gains mass.

What does Heisenberg's Uncertainty Principle state?

• The position and momentum of an electron can be known simultaneously.

• The position and momentum of an electron cannot be known simultaneously.

• Electrons have fixed orbits.

• Electrons emit light when excited.

What is Hund's Rule regarding electron configuration?

• Electrons fill the lowest energy orbitals first.

• Electrons only double up in orbitals if all orbitals first have one electron.

• Electrons are paired in orbitals.

• Electrons have fixed energy levels.

What is the value of Avogadro's Number?

• 6.626 x 10^{-34}

What is the formula for calculating light energy using frequency?

• E = h/f

• E = h + f

• E = h * f

• E = h - f

What is the difference between diamagnetic and paramagnetic substances?

• Diamagnetic substances have unpaired electrons; paramagnetic substances have all paired electrons.

• Diamagnetic substances are attracted to magnetic fields; paramagnetic substances are repelled.

• Diamagnetic substances have all paired electrons; paramagnetic substances have one or more unpaired electrons.

• Diamagnetic substances emit light; paramagnetic substances absorb light.
