When an electron moves from a lower to a higher energy level, the electron

• always doubles its energy.

• absorbs a continuously variable amount of energy.

• absorbs a quantum of energy.

• moves closer to the nucleus.

In Bohr's model of the atom, where are the electrons and protons located?

• The electrons move around the protons, which are at the center of the atom.

• The electrons and protons move throughout the atom.

• The electrons occupy fixed positions around the protons, which are the center of the atom.

• The electrons and protons are located throughout the atom, but they are not free to move.
