Explain the relationship between electrons, energy, and electromagnetic radiation.

• Electrons absorb energy and emit electromagnetic radiation when they move to a higher energy level.

• Electrons release energy and absorb electromagnetic radiation when they move to a lower energy level.

• Electrons neither absorb nor emit energy when interacting with electromagnetic radiation.

• Electrons only emit energy without any interaction with electromagnetic radiation.

What makes an atom stable and what might an atom do to become stable? Identify which elements are already stable and why.

• An atom is stable when it has a full outer electron shell, and it may gain, lose, or share electrons to achieve this. Noble gases are already stable because they naturally have full outer electron shells.

• An atom is stable when it has an equal number of protons and neutrons, and it may change its number of protons to achieve this. Alkali metals are already stable because they have one electron in their outer shell.

• An atom is stable when it has more electrons than protons, and it may gain protons to achieve this. Halogens are already stable because they have seven electrons in their outer shell.

• An atom is stable when it has a full inner electron shell, and it may lose electrons to achieve this. Transition metals are already stable because they have partially filled d subshells.

Differentiate between Bohr’s model of the atom and the quantum model of the atom.

• Bohr's model describes electrons in fixed orbits, while the quantum model describes electron probabilities in orbitals.

• Bohr's model is based on electron clouds, while the quantum model uses fixed paths for electrons.

• Bohr's model incorporates the uncertainty principle, while the quantum model does not.

• Bohr's model uses wave functions, while the quantum model uses particle trajectories.

Summarize the organization of the first three shells of the electron cloud. Include their orbitals and how many total electrons they can hold.
