Section 4.1 Quiz: The Development of a New Atomic Model

According to the Bohr model of the atom, which particles are allowed to exist in any one of a number of energy levels?

• electrons

• protons

• neutrons

• Both (b) and (c)

The line-emission spectrum of an atom is caused by the energies released when electrons

• “jump” from a lower energy level to a higher energy level.

• “jump” from a higher energy level to a lower energy level.

• “jump” from the ground state to an excited state.

• None of the above

• does not release energy.

• releases energy of only certain values.
