Why does a noble gas glow when it is energized

When the external power supply circuit is turned on, the output of the transformer will generate a high voltage of thousands of volts or even tens of thousands of volts. When this high voltage is applied to the electrodes at both ends of the neon tube, the charged particles in the neon tube are accelerated in the high-voltage electric field and fly towards the electrodes, which can excite a large number of electrons. These excited electrons are accelerated in a high-voltage electric field and collide with the gas atoms inside the lamp.

When these electrons collide with the energy of the free gas atoms and the energy is large enough, the gas atoms can be ionized and become positive ions and electrons, which is the ionization phenomenon of gas. When charged particles collide with gas atoms, the excess energy is emitted in the form of photons, which completes the whole process of lighting up the neon sign.

When an electric force is applied to excite a high-speed electron, the electron will emit light when it collides with a Greek gas. The energy required for the electrons in the outer shell of different gases is different, the electrons hit the gas is hit on the outer electrons, and the outer electrons are stimulated to radiate electromagnetic waves outward, and this electromagnetic wave is visible light, so we will see the light, and the inconsistency of the energy required causes the frequency of the excited light to be different, so the color is different.

Energizing makes the electrons of the noble gas active, and the electrons in each layer transition from high to low energy levels, producing gamma particles and photons, so there is visible light, and the color is different because the different electron energy levels of the noble gas are different, and the frequency of the gamma particles produced is different.

Its outermost electron gains an energy level transition, and its reverse process releases energy to emit light of a specific wavelength, which is simply the photoelectric effect.

Noble or noble gases refer to the 18 group elements on the periodic table (the new IUPAC regulations, i.e. the original group 0). At room temperature and pressure, they are all colorless and odorless monoatomic gases, which are difficult to carry out chemical reactions.

There are six naturally occurring noble gases, namely helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (XE) and radioactive radon (RN). OG is a synthetic rare gas with a very unstable nucleus and a short half-life (5 milliseconds).

According to the periodic law, it is estimated that OG is more reactive than radon. However, theoretical calculations show that it can be very reactive and not necessarily a noble gas. However, the carbon group element Fl (formerly tentatively named UUQ) exhibits similar properties to noble gases.

<> helium glows orange-red when energized.

Neon gas glows with electricity and is red.

Argon gas luminescence is blue-purple.

Krypton gas is yellow-green when it is electrified.

Xenon glows with electricity and is the same color as sunlight.

Radon luminescence is a radioactive gas and is not used as a light source.

Noble gases include: helium, neon, argon, krypton, xenon, and radon, which are 6 elements of the periodic zero group. 6 elements found in the late 19th and early 20th centuries air content (volumetric meter):

Argon, neon, helium, krypton, xenon, radon.

The decay products of radioactive minerals contain very little gas in air, so they are called dilute gases.

Noble gases are energized and luminescent physical changes. Noble gases are gases made up of group 0 elements on the periodic table. At room temperature and pressure, they are all colorless and odorless monoatomic gases.

Noble gases are gases made up of group 0 elements on the periodic table. There are seven noble gases, which are helium (He), neon (Ne), argon (Ar), krypton (Krypton), xenon (Xe), radon (RN, radioactive), and gas (OG, radioactive, man-made element).

Noble gases emit light when energized. The world's first neon sign was filled with neon gas (the original meaning of neon sign in English is "neon scattered and closed"). The red light emitted by the neon lamp is very transmitting in the air and can pass through dense fog.

Due to the relative content of various gases, a variety of neon lights are produced.

Commonly used fluorescent lamps are made by filling a small amount of mercury and argon in the lamp and coating the inner wall with a fluorescent substance (such as calcium halophosphate). When energized, ultraviolet rays are produced in the tube due to the discharge of mercury vapor, which excites fluorescent substances, and cracks to make it emit visible light similar to sunlight, so it is also called a fluorescent lamp. Krypton reduces the evaporation rate of filaments and is commonly used in high-performance incandescent lamps with higher color temperature and efficiency.
