Answer

Brief Explanations:

  1. Ground state: The ground state is the lowest - energy state of an electron in an atom. Electrons typically stay in this state unless they gain energy.
  2. Excited state: An excited state is when an electron is in a higher - energy shell. Electrons can gain energy, for example, through heat or electricity, and move to a higher - energy shell.
  3. Emission: Emission occurs when electrons in excited states lose energy and return to the ground state. The energy lost is emitted as light, and the energy of the emitted light matches the difference between the excited state and the ground state.
  4. Absorption: Absorption is when an electron in the ground state gains the right amount of energy to move to a higher - energy shell. This is called absorption as the electron absorbs energy.
  5. Steps in light emission: First, electrons gain energy (e.g., from heat in a flame test) and move to excited states. Then, since electrons are unstable in excited states, they return to the ground state. As they return, they emit light with energy equal to the energy difference between the excited and ground states.

In the flame test, different atoms emit different colors of light because each atom has a unique set of energy levels. When atoms are heated in a flame, their electrons are excited to different energy levels. As the electrons return to the ground state, they emit light of specific wavelengths (colors) corresponding to the energy differences in that particular atom. We see different colors separately or as an overall color in the flame test depending on the mixture of elements and the intensity of the emitted light from each element.

Answer:

  1. The ground state is the lowest - energy state of electrons in an atom.
  2. The excited state is when electrons are in higher - energy shells after gaining energy.
  3. Emission is the process of electrons in excited states losing energy and emitting light as they return to the ground state.
  4. Absorption is when electrons in the ground state gain energy to move to higher - energy shells.
  5. Steps in light emission: Electrons gain energy and move to excited states, then return to the ground state and emit light with energy equal to the energy difference between the states. In the flame test, different atoms emit different colors because each has unique energy levels. We see different colors separately or as an overall color depending on the elements and light intensity.
