When light hits an atom the atom absorbs certain wavelengths of light and reflects others. Upon gaining energy from light the electrons in the atom are elevated to a higher energy state. Upon returning from this state to the ground state the electrons lose energy in the form of a photon (which may be within the visible spectrum). As different elements have different gaps between each energy level, different elements will have different wavelengths of photon given out and thus different emission spectrums.

∙ 14y agoOk so basically electrons revolve around the nucleus in fixed paths called orbits (Orbits are called energy levels). As long as the electron stays in any one energy level it neither gains nor loses energy. However if the electron absorbs energy(light,heat,electricity) it jumps to a higher energy level. This electron is now called an 'excited electron'. Excited electrons are very unstable and eventually fall back to the original energy level that it came from (it's ground state). Energy is emitted when the electron falls back into it's ground state.
Since each electron can only fall back to certain definite energy levels, only fixed amounts of light can be given out. Every element has a different number of electrons with different electron transitions occurring so every element has a unique spectra!

∙ 12y agoThe colors emitted (or absorbed) are due to the narrowly-banded permissable energy levels within the electron configuration of the atom of the element. The electron configurations of each element are unique to that element and thus each element has its own unique (or "signature") range of colors emitted (or absorbed).

Each element will give off the same spectrum of light?
NO!!!! Each element gives off a unique spectrum of light.
What would be observed if the flame tests were viewed through a spectroscope?
Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc
Is Black comprised of every color in the spectrum?
yes
How does the color of the light bulbs determine the amount of energy of the electromagnetic waves?
The "color" is really a wavelength. The electromagnetic spectrum determines this, every different wavelength has a corresponding color. Red being the longest, and violet being the shortest. This electromagnetic spectrum also determines whether it is visible, ultraviolet, infrared, and so on.
How fast do electromagnetic travel?
Every wave in the electromagnetic spectrum travels at 2.99792x108 metres per second.
What element can produce an atomic emission spectrum in its natural state neon chlorine silicon or Krypton?
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
What spectum is obtained When any element in the gas phase is excited to the point where it emits visible light?
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.
Is it true that each element has a unique set of lines on a spectrum?
Yes , every element has different line in the spectrum.
How can scientists use light to identify an element?
Every element has a unique emission spectrum. The lines in these spectra deduce the amount of energy released during electron transition from a higher energy level to a lower. After obtaining this spectrum, the scientists can compare them with their tabulated data.
How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
Each element will give off the same spectrum of light?
NO!!!! Each element gives off a unique spectrum of light.
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.
Does Every element and compound in nature have a unique set of spectral lines?
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
What is the principle of PMI testing?
The XRF-principle (x-ray fluorescence) is the method for PMI. Equipment used contains low radioactive sources (isotopes) or x-ray tubes. The exposed material reflects the radiation, generating energy. As every element has it's own atomic structure, this reflection will generate a different energy level for every element. This energy is measured and detected, thus identifying the alloy elements. The other method for PMI is Spark emission spectrography. Spectography is based on optical emission. The equipment consists of a probe which releases a spark that is used to vaporise the material being analysed. The atoms and ions in this vapour produce a spectrum which can be optically measured and then recalculated to determine the components of the material
Are the number of electrons different from every atom of every element?
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
Is sodium the only element with eleven protons?
Yes. Every element has a different number of protons.
What makes oxygen element different from other element?
It is the same for each and every element, it's the number of protons in the nucleus of one atom of the element.
