What does “Hydrogen energy levels” actually mean in Atoms, and why does it matter for JEE?
Hydrogen bound-state energies are negative because zero is assigned to a free electron at infinity. Larger n means less negative energy and weaker binding.
In simple words: Hydrogen bound-state energies are negative because zero is assigned to a free electron at infinity. Larger n means less negative energy and weaker binding. Getting Hydrogen energy levels clear matters because JEE questions on Atoms usually test this idea directly, not just a formula you memorised.
Key point
Hydrogen energy levels
Common mistake
thinking n = infinity is the most tightly bound state.
Memory tip
n = 1 is deepest; n = infinity is ionised.
