Electron Configuration Review

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