If a gas fire gives off a green flame, is that a bad thing? Each element give off a particular color when heated in a flame. (Some are colorless). Copper gives off a green flame but to do that there must be some copper compound IN the flame. (there are many other elements that also could be causing a green flame).

- Exciting Electrons using LIGHT. When metals or metal salts are heated in a flame, the flame becomes highly coloured. These colours are due to the electrons getting excited! Fireworks are made up of metal salts-they take advantage of the different colours that are produced when metal ions or atoms are heated. Lithium (left), sodium (middle) and copper (right) salts give pink, yellow and green flame colours.

- Every gas creates a different color of light: helium-orange/white, neon-red/orange, argon-lavender, krypton-gray/green, and so on. The colors of auroras are determined by the gases in the Earth's atmosphere, and incoming solar particles tend to collide with different gases at different heights. Very high up (above 300 km / 185 miles), oxygen is the most common gas, and collisions there can create a rare red aurora.very gas creates a different color of light: helium-orange/white, neon-red/orange, argon-lavender, krypton-gray/green, and so on.

PHOS-PHO-RUS Phosphorus is another one of those elements that you will never find free in nature. It is very reactive. When isolated and pure, phosphorus is clear and almost transparent. There are four common forms of phosphorous used today: white, black, red, and violet. It's easy to spot phosphorus on the periodic table just under nitrogen (N) at position number fifteen. You can find phosphorus in baking powder, fertilizers, and fireworks. > More about the orbitals and compounds of phosphorus.

Colored fire Colored fire. Emitted colors depend on the electronic configuration of the elements involved. Heat energy from the flame excites electrons to a higher quantum level, and the atoms emit characteristic colors (photons with energies corresponding to the visible spectrum) as they return to lower energy levels.

- Burning Magnesium. Magnesium is one of the alkaline-earth metals, and is one of the most common elements in the Earth's crust. In its pure form, it is silvery white, and relatively soft. It burns in air with a brilliant white light, and for this reason is often used in flares and fireworks.2Mg(s) + O 2.Mg(s) + N 2 3 N 2 (s). Magnesium also burns in an environment of carbon dioxide such as in a beaker full of dry ice: 2Mg(s) + CO 2. Magnesium is used in disposable flash bulbs to generate light for photography, but this use has been largely supplanted by other sources of illumination.

Colored Fire - Where to Find Metal Salts for Colorants Yellow-Your usual fire will be yellow already, but if you are burning a fuel that produces a blue flame, for example, you can turn it from green to yellow by adding sodium salt, such as common table salt. Orange-Calcium chloride produces orange fire. Calcium chloride is sold as a dessicant and as a road de-icing agent. Just be sure the calcium chloride isn't mixed with sodium chloride or else the yellow from the sodium will overpower the orange from the calcium. Red-Strontium salts produce red colored fire.

- That's chemistry too! Fireworks get their color from metal compounds (also known as metal salts) packed inside. You probably know that if you burn metals in a hot flame (such as a Bunsen burner in a school laboratory), they glow with very intense colors— that's exactly what's happening in fireworks.

Q & A: Uses and dangers of radioactive elements Some radioactive elements glow because of their radioactive decays. They emit electrons or alpha particles, changing from one kind of element to another, and as the electrons in the atoms rearrange themselves to the new atom's configuration, they emit light. Radium was used for watch dials because it glows green.articulrly nasty radioactive elements include radon and radioactive iodine. Radon is a chemically inert gas with a short half-life (and therefore decays rapidly, emitting radiation faster than other elements).

Why do different elements make different color flames when you burn them? Different elements have different flame colours because their electrons have different allowed energy levels. > The Bohr model says that electrons exist only at certain allowed energy levels. When you heat an atom, some of its electrons are excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. The wavelength (colour) of the light depends on the difference in the two energy levels. We can see only those transitions that correspond to a visible wavelength. In a hydrogen atom, for example, we can see only the transitions from higher levels to n = 2 (the Balmer series). Every element has its own characteristic set of energy levels. Thus, an atom of Na has different energy levels and transitions than an atom of Li. The different mix of energy differences for each atom produces different colours.

Flame tests Flame tests are useful because gas excitations produce a signature line emission spectrum for an element. In comparison, incandescence produces a continuous band of light with a peak dependent on the temperature of the hot object.ecause each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame.

Why Are There Blue and Green Flames? And copper is absolutely not the cause of blue gas flames on a kitchen stove or the blue inner core of a candle flame. From now on, any mention of blue or green flames will refer only to flames not involving copper or barium, or any other element that gives off blue or green wavelengths.
