which model is bohr credited with developing ?
○ the periodic table
○ the orbital model of the atom
○ the plum pudding model of the atom

Explanation:

First Question (What may happen to the electron when it gains energy?)

• Analyze Option 1: Electrons drop to lower energy levels when they lose energy, not gain. So this is incorrect.
• Analyze Option 2: Electrons can change their energy levels (and thus location in terms of energy shells) when energy is gained or lost. So this is incorrect.
• Analyze Option 3: When an electron gains energy, it has the potential to move from its current energy level to a higher (more energetic) energy level. This matches the concept of electron excitation.

• Analyze Option 1: The periodic table was developed by Dmitri Mendeleev, not Bohr. So this is incorrect.
• Analyze Option 2: Niels Bohr developed the Bohr model (also called the orbital model of the atom in a simplified sense, focusing on electron orbits around the nucleus with specific energy levels). This is correct.
• Analyze Option 3: The plum pudding model was developed by J.J. Thomson, not Bohr. So this is incorrect.

Answer:

It may move to a higher energy level.
