When any element is excited to the point where it emits visible light, it emits a unique spectrum. The Mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.
The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.
You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.

Which portion of the electromagnetic spectum can be viewed with the bare human eye?
The visible light spectrum (wavelengths from 380 to 700 nanometers)
Why do different elements emit different colors when they are heated?
because when elements are heated there electrons become excited and jump through the elements "steps" and as they become less excited the jump back down steps emitting a unique wavelength and the visible wavelength is the colour we see -------------------------------------- The wavelength of the spectral lines emitted by different elements are specific for each element. Consequently the colour is also different.
How is an atomic spectra produced?
Electrons move between different energy levels in an atom. When electrons are in the lowest orbital, otherwise known as the ground state, they eventually progress into the highest orbital, also known as the excited state. When electrons move from the excited state back to the lowest orbital, they emit energy in the form of light that varies in colors, depending on the element. Some of these forms of light may not always be visible to the naked eye.
Does a fluorescent bulb specificaly phosphorus reflects ultraviolet radiation.?
There is no phosphorus in a fluorescent lamp, the coating is a compound called phosphor.phosphorus is an element that burns.phosphor is a compound that when excited by an electron beam, UV light, or x-rays glows in visible light.A fluorescent lamp is a mercury vapor UV (aka black light) lamp with a phosphor coating on the inside of the lamp tube to turn the invisible UV light to visible light.
Visible light given off by excited atoms and molecules in the upper atmosphere?
The Aurora Borealis (Northern Lights) and the Aurora Australis (Southern Lights).
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
What visible light color is strongly absorbed by chlorophyll?
Predominantly red and blue spectum, green is refelcted
Which portion of the electromagnetic spectum can be viewed with the bare human eye?
The visible light spectrum (wavelengths from 380 to 700 nanometers)
What energy is a light?
light energy is any visible form of energy that forms part of the electomagnetic spectum it is therefore transmitted as any form of electromagnetic wave.
Why does lithium chloride turn pink over a flame?
because the electron jumps made in lithium chloride give out a reddish color when moved to the excited state of the visible light spectrum. the heating moves them up to the excited state
How is the electromagnetic spectrum related to sight?
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.
How is visible light made?
Light is emitted when an electron drops from the orbit of an excited state, into its natural state. The quantum of light emitted is characteristic of the change in energy of the two electron states, and also of the actual element involved.
Result obtained when bromine is added to potassium chloride?
No visible reaction
What properties does visible light have in common with the rest of the electromagnetic spectrum?
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.
If you cut a metal element over and over again until it is not visible would it still be an element?
Yes
Why do different elements emit different colors when they are heated?
because when elements are heated there electrons become excited and jump through the elements "steps" and as they become less excited the jump back down steps emitting a unique wavelength and the visible wavelength is the colour we see -------------------------------------- The wavelength of the spectral lines emitted by different elements are specific for each element. Consequently the colour is also different.
Why is visible light given off when a salt such as sodium chloride is exposed to a flame?
excited electrons returning to the ground state.
