Arrangement of Electrons in Atoms Review

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

Because excited hydrogen atoms always produced the same line-emission spectrum, scientists concluded that hydrogen

• has no electrons

• does not release energy

• releases energy of only certain values

• can exist only in the ground state
