Answers & Comments
Answer:
1. The colors of light emitted by metals are related to the structure of the atom through the quantum mechanical model. When electrons in an atom absorb energy, they move to higher energy levels or orbitals. When they return to lower energy levels, they emit energy in the form of light. The specific colors of light emitted correspond to the energy differences between these levels, which are characteristic of the atom's structure.
2. Bohr's atomic model introduced the idea of discrete energy levels or orbits for electrons within an atom. He explained that electrons move in these orbits without emitting radiation. When an electron transitions from one energy level to another, it emits or absorbs energy in the form of photons of specific frequencies. These frequencies correspond to the energy difference between the energy levels.
3. Electron configuration refers to the distribution of electrons within the energy levels and sublevels of an atom. It describes the arrangement of electrons in various orbitals around the nucleus.
