Elements whose atoms give off radiation are called?
Radioactive elements give off radiation. The emission of radiation occurs when an unstable atomic nucleus tries to become stable. Some examples of radioactive elements are radium, curium, nobelium, rubidium, and polonium.
What is a flame test?
Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer. A method of obtaining an emission spectrum from a sample
How astronomers can identify the gasses found in a planet's atmosphere explain?
It's by analzying the spectrum of light reflected off the planet, through a method called spectroscopy. Different elements absorb light energy at different wavelengths, and re-emit light at specific, well-characterized wavelengths. By analyzing the light reflected off a planet, scientists can work out the most abundant elements in its atmosphere.
How do astronomers use the the spectrum of an object to gain information about what object's made of?
Take some pliers. Take a pin. Take some salt and put it on the pin. If you can use the the pliers to hold the pin covered with salt over and real close to a source high heat, you might see a yellow color above the pin. That yellow tells you that the product contains sodium. Scientists can look for that particular color and tell that it comes from something that contains sodium. Other elements give off different colors. By seeing what colors items give off, scientists can tell what something is made of. We used sodium because it is simply the easiest one to see.
What type of energy do fossil fuels give of?
It give off Carbon Dioxide (CO2)
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.
Element discovered by Bunsen and kirchoff?
Rubidium and Cesium. Rubidium was found to give off an emission spectrum of Ruby-Reddish.And Cesium with a bluish-purplish emission.
Why does a gas give off an emission spectrum when it absorbs energy?
It doesn't. An absorbtion spectrum is produced when it absorbs energy. An emission spectrum is produced when it lets the energy go again. The energy changes are associated with the element's electrons going up to higher energy levels and then dropping down again.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
Do all heated elements give off light in the visible spectrum?
no it depends on the energy level the electrons are jumping down to
Does the sun give off a discontinuous spectrum?
No. The sun gives off a full continuous spectrum.
Elements whose atoms give off radiation are called?
Radioactive elements give off radiation. The emission of radiation occurs when an unstable atomic nucleus tries to become stable. Some examples of radioactive elements are radium, curium, nobelium, rubidium, and polonium.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
What is a flame test?
Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer.

Very dense material when heated will give off a spectrum?
if using sunlight, will give off a continuous specturm
Why is the emission spectrum of hydrogen made of discrete wavelengths rather than a continum of wavelengths?
The emission spectrum of all elements is made of discrete wavelengths. Electrons only exist in particular orbitals. They do not spin willy-nilly around the nucleus. If they receive energy, they jump from one orbital to a higher orbital. When they fall back to a lower orbital, they give off a discrete amount amount of energy. That discrete amount of energy comes as the form of light of a particular wavelength. Look at it as an electron having to be on one or another step instead of a ramp. Instead of continually rolling, it goes one step at a time.
How is the light given off by fireworks similar to an element's emission spectrum?
Many firework colors are made by burning metal salts. Each element gives off a unique color of the spectrum. When fireworks are lit, it causes the atoms of the metal salts to become excited, and as the fireworks are shot into the air electronic transition takkes place and visible light is seen. Depending on what elements the firework is made of will determine the color seen.
