The simple answer is that when the outer electrons in an atom change their energy state they can only do so in discrete amounts. When they do this a photon is emitted. The photon has a wavelength corresponding to the energy that it carries. We see colour because of this wave length. The electrons in any different atoms are always in different quantum states. All electrons in smiler atoms have the same series of energy levels and so emit the characteristic wave spectrum for that atom. This is the basis of spectrometry.

Why does a sodium street lamp give off a yellow color whereas a neon light gives off a red color?
Sodium lamps produce yellow light because they contain sodium vapor that emits light at a specific wavelength when electrified. Neon lights give off red light because they contain neon gas that emits red light when excited by electricity. The difference in colors is due to the unique emission spectra of each element.
Can you use flame test to identify element?
Yes. Every element has a very particular emission spectrum. Each element has a specific structure of nucleus and electron orbits. Because of this, when a certain element is ionized (ie. by a flame), the electrons rejoining with the nuclei give off a specific frequency of light. The color of light witnessed after burning the compound is an indicator of the elements present.
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.
Why does combining a secondary color with its complementary color give white light?
When a secondary color is combined with its complementary color, the mixture includes all three primary colors (red, green, and blue) in equal proportions. These primary colors combine to produce white light because they cover the entire spectrum of visible light when mixed together.
Why do solutions have color?
Some solutions have color due to the presence of certain compounds that absorb and reflect light at different wavelengths. This absorption and reflection of light can give solutions their characteristic color. The color of a solution can provide information about the chemical composition of the solute dissolved in it.
What can you now say about the spectra from various light sources?
The light source will give a spectrum that shows what elements are present. Each element will give of a particular colour, almost like a fingerprint.
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.
Which element gives mars its reddish orange color?
the Element that give mars its color is titaniasflkas and wat ever els is on that planet
What color it emitted by potassium?
In a flame test, the color released by potassium is lilac, which is a light purple. K is the symbol for the chemical element potassium, and its atomic number is 19.
Why does an element give off light of a particular colorwhen flame test is being conducted?
This is because each element has different photons (bundles of light) it gives off during reaction or energy transfer. For example, lithium has primarily red photons, so you see a lithium flame as red.
What element give mars it's reddish-orange color?
Carbon and iron
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.
Why does a sodium street lamp give off a yellow color whereas a neon light gives off a red color?
Sodium lamps produce yellow light because they contain sodium vapor that emits light at a specific wavelength when electrified. Neon lights give off red light because they contain neon gas that emits red light when excited by electricity. The difference in colors is due to the unique emission spectra of each element.
Give the importance of elements and compounds?
1.they give carbon dioxide and oxygen2.element is pure substance that cannot be broken3.in has light,an element is the simplest kind of matter
What element was found in chinchorro mummy masks?
Manganese, used to give a black color to the faces.
What color are dinoflagellates?
dinoflagellates give off light which is known as luminscent
How can you see an object which does not give out light?
You can see an object that does not give out light because it reflects light from another source, such as the sun or a light bulb. This reflected light then enters your eyes, allowing you to perceive the object's shape, color, and texture.
