In order to produce the light emission you need some extra energy to spend. The ground state is stable and transitions lower it are forbidden as a result no extra energy to spend.

What does line spectrum tell us?
The bright line emission spectrum tells us the amount of energy between the exited and ground state. When electrons move from an exited state to a ground state, radiant energy of a specific frequency is emitted this creates spectral lines.
If considering two different atoms explain the spectral lines?
Spectral lines are bright or dark lines in an otherwise continuous or uniform spectrum. They are caused by an excess (emission lines) or deficiency (absorption lines) of observed photons within certain frequency ranges. Absorption lines usually come from a background continuum; photons are absorbed when passing through matter to the observer. Absorption occurs when an electron within an atom absorbs a photons energy and is bumped up to an excited state. Emission lines usually come from hot gases; photons are emitted from these gases and reach the observer. Emission occurs when an electron within an atom falls back down to it's ground state and releases energy in the form of a photon.
What does the energy of spectral lines represent?
an emission spectrum is produced after atoms are supplied with electrical energy afterwhich they emit energies as they return to ground state after excitement. the emission spectrum is produced with coloured lines on a dark background. these lines all have different wavelengths thus different frequencies and different quantums of energy. each level has a different energy and since these lines show properties of different energies they show also that atoms have discrete energy levels.
Which of the following correctly explains how energy is emitted when an atom returns to the ground state?
There is insufficient information in the question to properly answer it. You did not provide the list of "the following". In general, however, if it is the nucleus that returns to ground state, then gamma ray emission is the mechanism. It it is the electron cloud the returns to ground state, then x-ray emission is the mechanism. The end result is the same - a photon is emitted with a certain energy - only the mechanism differs.
Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
What is argon used for in fieworks?
Argon is used to produce violet lights. Electrons in argon atoms use energy from the firework explosion to make the transition from the ground state to an excited state. Their return to the ground state results in the emission of violet light.

In which case will the woman see a just a spectrum that is almost entirely black except for few bright emission lines?
The spectrum that she will be observing is called an emission spectrum, in which electrons are excited to a higher energy state and then drop back down to the ground state, during which the electrons will emit photons of specific wavelengths, which will be observed as bright lines of color on what appears to be a black background.

What element can produce an atomic emission spectrum in its natural state neon chlorine silicon or Krypton?
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
What process makes an emission nebula glow?

What causes the emission of radiant energy that produces characteristics spectral lines?
When the electrons absorb energy from a source, such as heat, they move to an excited state (farther from the atoms nucleus). They then release the energy in the form of light which produces the observed spectral lines of color. Once the energy is released, the electrons move back to a lower energy level (ground state).
What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
What is happening within the hydrogen atom to create emission lines?
The electron in the atom becomes excited as something adds energy to it, moving it to a higher energy level. When the electron moves back to the normal energy level, called a ground state, it emits light of a given frequency.
