When we look at how classical and quantum models explain the atom, we see some big differences in how they describe its structure.

Classical Model:

• Imagine electrons like little planets moving around a central core, similar to how Earth goes around the Sun.
• It's based on classical physics, which makes it easy to picture in your mind.
• But there's a problem: this model doesn't explain why atoms stay stable. According to it, electrons should lose energy and get pulled into the core.

Quantum Model:

• In this model, electrons don’t move in fixed paths. Instead, they are found in areas called "orbitals," which are more like fuzzy clouds where they are likely to exist.
• This model uses ideas from quantum mechanics, which includes wave-particle duality, leading to something called the uncertainty principle.
• The quantum model explains why atoms are stable and how electrons behave much better than the classical model.

So, in short, the quantum model gives us a much clearer and more accurate picture of the atom than the classical model does!
