How is light produced when elements are heated to high temperatures?

This is particularly true to metals, and are the basis for flame tests and even for flame AAS analysis. When a metal is heated, the energy is taken in, and this promotes an electron to the lowest unoccupied molecular orbital (LUMO). When this electron falls back down to the highest occupied molecular orbital (HOMO) the energy is often released as light, with a wavelength proportional to the energy difference between the HOMO and LUMO.

When a strontium compound is heated in a flame red light is produced When a barium compound is heated in a flame yellow-green light is produced Explain why these colors are emitted?
Yes
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
Why do atoms of certain elements give off light of characteristic color when heated to high temperature?
Atoms of certain elements give off light of characteristic color when heated to high temperature since the electrons induce to absorb energy, jumps to the excited energy state called quantum jump and then returns to their ground state. The amount of energy in the photon determines its color.
What does every element emit if it is heated by passing an electric discharge through its gas or vapor?
A specific pattern of light. This permits elements to be identified by an instrument known as a spectroscope.
Conclusion in flame test?
During a flame test, elements are heated, and their, electrons of the atoms gain energy from the flame. When they lose this energy, they emit colors of visible light. Since each element has its own specific light, you can easily identify which element has been heated
When a strontium compound is heated in a flame red light is produced When a barium compound is heated in a flame yellow-green light is produced Explain why these colors are emitted?
Yes
How do neon lights produce colorful light?
Gases in them are heated into high temperatures.
What is light produced by?
A filament is heated by an electric current and photons are emitted.
What is light produced?
A filament is heated by an electric current and photons are emitted.
What type of energy is produced when a heated chemical glows?
Photons are emitted (light energy) and infrared energy.
Why do salts produce colors when heated?
The cause of the color is light (specific spectral lines) emitted by the metal from the salt at high temperatures.
How does the sun and all-stars create light and energy?
All stars contain Hydrogen and Helium. When heated to extreme temperatures, these become in the state of plasma. In this state, the elements are able to ignore their resistance towards each other and fuse into other elements. This process, nuclear fusion, gives off lots of electromagnetic energy (solar wind), and some of this can be seen as visible light.
What element is a light?
The light elements include Hydrogen, Helium, and Lithium. Some lists might include more. The light elements were initially formed in the big bang and current universal levels of hydrogen and helium agree very well with the levels produced in the big bang. Much less lithium was produced in the big bang, with most being produced later in stars. Elements past lithium were produced only later in stars.
Do all heated elements give off light in the visible spectrum?
no it depends on the energy level the electrons are jumping down to
Where does the energy for a light bulb come from?
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
Why do different elements give off a colorful light when heated?
The color depends on the lines of the emission spectrum of each different element.
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
