ONLINE ACTIVITY (QUIZ)

In the free electron model, electrons are assumed to move freely without any interaction with each other or the metal lattice.

• TRUE

• FALSE

The Fermi level represents the highest energy level occupied by electrons at absolute zero.

• TRUE

• FALSE

The Fermi-Dirac distribution function describes the probability of an electron occupying an energy state at any given temperature.

• TRUE

• FALSE

At absolute zero, all energy states below the Fermi level are filled, and all states above are empty.

• TRUE

• FALSE

The density of states in a metal decreases as energy increases.

• TRUE

• FALSE

In metals, electrons near the Fermi level primarily determine the metal's electrical conductivity.

• TRUE

• FALSE

In the Fermi-Dirac distribution, the probability of finding an electron at the Fermi energy is always 1.

• TRUE

• FALSE

The free electron model treats electrons in a metal as if they are in a potential well with finite barriers.

• TRUE

• FALSE

The Fermi energy of a metal increases as the temperature of the metal increases.

• TRUE

• FALSE

The Fermi-Dirac distribution function approaches the classical Maxwell-Boltzmann distribution at high temperatures.

• TRUE

• FALSE
