Question

what do electrons in the same shell have in common?
they have the same amount of energy.
they are all positively charged.
they are all made up of atoms.
they all have neutral charges.

Explanation:

• Analyze Option 1: Electrons in the same shell (energy level) have approximately the same energy. This is a key concept in atomic structure (electron configuration), where electron shells are defined by energy levels.
• Analyze Option 2: Electrons are negatively charged, so this is incorrect.
• Analyze Option 3: Electrons are subatomic particles, not made up of atoms. Atoms are made up of electrons, protons, and neutrons. So this is incorrect.
• Analyze Option 4: Electrons have a negative charge, not neutral. Neutrons are neutral. So this is incorrect.

Answer:

A. They have the same amount of energy.
