What type of energy does an element need to absorb to emit light?

Many different types of energy can do this.
Heat will cause anything to emit blackbody radiation and if there is enough heat the blackbody radiation will overlap the visible light spectrum and the object will be incandescent.
To emit light as a narrow spectral line requires raising electrons in the element to higher energy orbitals and allowing them to fall back, emitting photons. The type of energy that can do this can be of many sorts: light, chemical, electrical, etc.

What acid burns green in a Bunsen burner?
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color. Boron gives off a green color.
When a vehicle is slowing down what changes its momentum and kinetic energy as force of brakes is an internal force?
Brakes absorb the kinetic energy in the form of heat and sometimes sound. When hot enough brakes can emit light.
Do atoms absorb the same energy?
No, atoms do not absorb the same energy. The amount of energy an atom can absorb depends on its electronic structure and the specific energy levels of its electrons. Different atoms have different numbers of electrons and different energy level arrangements, so they will absorb and emit energy at different wavelengths and energies.
The color of light given off when a sample is heated corresponds to?
heated of the element heat absorbed by the sample amount of energy added to the sample energy difference between the ground state and exited states of an element.
Why si and ge does not emit light?
energy levels wrong.
How is an emission spectrum of an element generated?
All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.
What substances absorb energy from an outside source and then emit some of it as visable light even after the source is removed?
phosphorescent materials do this
Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
If atom of a substance absorb ultraviolet light and emit red light what becomes of the missing energy?
The missing energy resides in the atom's excitedconfiguration, namely the electrons are orbiting at a higher quantum orbit.
Do atoms in an incandescent gas absorb or emit light?
When they exit their exited state. When an atom is bombarded by photons, it will often times absorb the photon. A photon is a unit of energy, so this energy is added to the atom, "extiting" it. However, atoms may only remain in ths excited state for a short period of time, and will eventually release the photon, reemiting it as light, and then the atom will return to its normal state.
Wavelenghts at which planets emit enregy?
Most planets absorb energy in the light and UV (and shorter) wavelengths. Planets radiate energy in the infrared (heat) and longer wavelengths.
Why would the core of a star emit light and the outer atmosphere of a star absorb it?
The core would emit light because it is hot. The outer atmosphere would absorb light because it is not completely transparent. It would also re-emit radiation itself, because of its heat.
What does re radiate mean?
To absorb some amount of radiative energy, and then later emit that energy in the form of radiative energy. The term is most often used in discussion of absorption of light or infraredradiation.
Why is helium a greenhouse gas?
because it can absorb and re-emit the suns energy
Is helium a greenhouse gas?
because it can absorb and re-emit the suns energy
How can you can increase or decrease the energy possessed by electrons?
Electrons can absorb photons and gain energy, and they can emit photons and lose energy.
What happens when electron jump from atom to atom?
It will absorb or emit energy, according to the difference in the corresponding energy levels.
