∙ 9y agoAny form of energy in the electromagnetic spectrum can be emitted. The form will correspond to the amount of energy emitted.

When an electron in an atom moves from a lower energy state to a higher state?
An electrons moves from lower energy to higher energy when it is excited.
The line emission spectrum of an atom is caused by the energies released when electrons?
The line emission spectrum of an atom is caused by the energies released when electrons fall from high energy level. It goes down to a low energy level and the extra energy it had from higher level is released as light.
Why do atoms emit only certain wavelengths of light?
The electrons in an atom's "electron shell" all have specific energy levels. If you add energy to an atom, the atom will absorb a specific amount of energy, and the electron will jump up to a higher energy level. Each different element has its own energy levels, and it can only absorb energy in specific amounts. (When you add a lot of energy to the atom, the atom becomes ionized, as one or more electrons absorb enough energy to break free of the atom completely, leaving the atom with an unbalanced positive electrical charge.) When those "excited" or jumped-up electrons release the energy, the electron drops back to its previous level, and the atom (or more specifically, the electron) emits a photon, which is a particle of light. Each photon has a frequency or energy that is distinctive to the element and the energy level. Electrons cannot have intermediate energies; they absorb and release exact "packets" or "quanta" of energy. This is how a mass spectrometer works; the operator ionizes a sample of the material that he wants to analyze, and watches the resulting spectrum. Each wavelength of light emitted by the sample corresponds to one specific element.
Explain why ionized calcium can form absorption lines but ionized hydrogen can not.?
every atom can absorb light at different specific wavelengths (a useful fingerprint), these wavelengths correspond to the amount of energy it takes to move the atom's electrons from their ground state to an excited state, this is the cause of absorption lines. the atom will soon emit the light again (at the same wavelength, as the electron moves from excited to ground states), but in a random direction, this is the source of emission lines. an ion is an atom that has lost one or all of its electrons. in the case of a calcium ion, there are still some electrons present, atomic hydrogen has only one electron, so once it becomes ionised there are no electrons to create absorption lines.
What is the difference between emission and absorption?
Emission is something be spread out, while absorption is something being taken in.
What event accompanies energy absorption by chlorophyll?
An electron is excited
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 kind of spectrum is produced when the electron jumps form a high energy state to a lower energy state?
When an electron moves to a lower energy level, the difference in energy appears in the form of a photon, which the electron emits.
If an electron has absorbed energy and has shifted to a higher energy level the electron is said to be what?
This electron is called excited.
What event accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex?
The event that accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex is the excitation of electrons. When light energy is absorbed by the pigment molecules, their electrons get excited to a higher energy state. This excited state is essential for the subsequent transfer of energy to the reaction center of the photosystem for further processing.
What happens when an excited electron is passed to an electron acceptor in a photosystem?
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
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 determines an elements emission spectrum?
The electron energy levels.
Does an excited electron move up or down an energy level?
The excited electron move up.
Can an electron stay in an excited state without outside energy?
No, It is due to the fact that without energy an electron can not go to excited state.
What did Planck say about energy and electron?
He said that electrons can become excited and begin to hop energy levels; when this happens an electron is in the excited state.
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.
