Ground State: This refers to the lowest energy state of an atom or other particle. In our concert analogy, it would be those front row seats!
Excited State: This is when an electron absorbs enough energy to move from its normal state into a higher-energy orbital - kind of like getting bumped up from regular seating at a concert into VIP!
Electron Configuration: This describes how electrons are distributed among atomic orbitals - think about it as who sits where during our concert.
