Electrons reside in orbits.They move between each shell when gaining or losing energy
Answer (1)
This is a description of the Bohr Model of the atom, proposed by Niels Bohr in 1913. In this model:Electrons orbit the nucleus in fixed energy levels or "shells".When an electron gains energy, it jumps to a higher energy level (excited state).When it loses energy, it returns to a lower level, releasing energy often as light.Example:In fireworks, electrons absorb heat, jump to a higher shell, then fall back and emit colorful light.This model helps explain the color spectrum of elements and how atoms interact with energy.
