What is the effect of an atom gaining electrons?
The atom becomes a negatively charged ion (anion).
What is the effect of an atom losing electrons?
The atom becomes a positively charged ion (cation).
What happens when an electron transitions to a lower energy level?
A photon is emitted.
What happens when an electron absorbs a photon with the correct energy?
The electron transitions to a higher energy level.
Briefly describe how ions are formed.
Ions form when atoms gain or lose electrons, resulting in a net electric charge. Losing electrons forms cations (positive ions), while gaining electrons forms anions (negative ions).
Describe how electrons transition between energy levels in the Bohr model.
Electrons can jump from one energy level to another by absorbing or emitting photons with energy equal to the energy difference between the levels.
