Question

Energy is added to an atom, and light is produced. Which of the following best

explains why this happened?
The added energy come from a flame or electricity. Fire and electricity always
produce light.
When an atom absorbs energy it causes the atom to temporarily absorb an extra
electron in a higher energy level. This electron is unstable, as it is not normally a
part of this atom. This unstable electron in the excited state quickly returns to
where it came from and leaves the atom, causing light to be released.
The atom absorbed energy. Light was produced as this energy is absorbed
because the added energy caused an electron to move to a higher energy level.
The electron existing in this higher level is called the excited state. This jump to a
higher energy level is seen as a photon of light.
The added energy is absorbed by the electrons in the atom. This causes the
electrons to move to higher energy levels where they are unstable. As the
electrons return to their original energy level, the absorbed energy is released in
the form of a photon of light.

Answer 1

The most accurate explanation among the options provided is:

The added energy is absorbed by the electrons in the atom. This causes the electrons to move to higher energy levels where they are unstable. As the electrons return to their original energy level, the absorbed energy is released in the form of a photon of light.

When energy is added to an atom, such as through heat or electricity, the electrons in the atom can absorb this energy and move to higher energy levels. However, these higher energy levels are unstable, and the electrons cannot remain in them for long. They quickly return to their original energy levels, releasing the absorbed energy in the form of a photon of light. This process is known as emission of light or luminescence.
