Ionic Bonding FAQ: Valence Electrons 2

TL;DR

Energy levels in atoms are not physical structures, but rather exist because of the presence of electrons.

Transcript

okay here's another question it's really good sometimes people say okay when you empty this valence energy level out okay so there are no more electrons in it it's not a valence energy level anymore and they say what happens to it okay like in this diagram I just kind of pull it off the atom like this and say we don't have to worry about any and pe...

Key Insights

• 🫀 Energy levels in atoms are not physical structures but a representation of electron arrangement.
• 🍃 Electrons leaving an energy level cause it to cease existing, just like cars leaving a row in a parking field.
• 😨 The analogy of parking cars in an unmarked grass field helps understand the concept of energy levels in atoms.
• 🥹 Energy levels do not have marked spaces or physical boundaries to hold electrons.
• 🛫 The disappearance of an energy level signifies the departure of electrons from a specific arrangement.
• 🤔 Understanding energy levels requires a shift in thinking and acknowledging their non-physical nature.
• 🎚️ The number of electrons that can fit in each energy level is not determined by physical compartments but by electron capacity.

Questions & Answers

Q: What happens to the valence energy level when all electrons leave it?

The valence energy level ceases to exist as it is not a physical structure, but rather a representation of electron presence. It is comparable to a row of parked cars disappearing when the last car leaves.

Q: How do atoms get rid of an energy level?

Atoms get rid of an energy level when electrons leave it. The energy level vanishes as it is not a physical thing, but rather a result of electron arrangement.

Q: What is the purpose of drawing energy levels with holes if they don't physically hold electrons?

Drawing energy levels with holes helps in understanding how many electrons can fit in each level. However, it is important to remember that the holes are not physical structures but a representation of electron capacity.

Q: Can energy levels in atoms be compared to plastic rings with cups that hold electrons?

No, the analogy of plastic rings and cups is not accurate. Energy levels in atoms do not have physical cups or structures to hold electrons. They exist because of the presence of electrons and vanish when electrons leave.

Summary & Key Takeaways

• Energy levels in atoms are not physical entities, but rather a representation of electron arrangement.

• Electrons leaving an energy level cause it to cease existing, similar to cars leaving a row in a parking field.

• The analogy of parking cars in an unmarked grass field helps understand the concept of energy levels in atoms.
