Electrons in Atoms Lesson

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.

• 1s²2s²3s²3p⁶3d¹
• 1s²2s²2p⁶3s²3p⁶4s¹
