Hydrogen

Those 11 gases are Helium, Argon, Neon, Krypton, Radon, Xenon, Nitrogen, Hydrogen, Chlorine, Fluorine, and Oxygen. These are called pure gases as they are all elements. You can use these names as the perfect example of gas matter.

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

The table indicates that nitrogen and oxygen are the main components of the atmosphere by volume. Together these two gases make up approximately 99% of the dry atmosphere.

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. The exosphere gradually fades away into the realm of interplanetary space.

thermosphere

Layers of the atmosphere

• The Troposphere. This is the lowest part of the atmosphere – the part we live in.
• The Stratosphere. This extends upwards from the tropopause to about 50 km.
• The Mesosphere. The region above the stratosphere is called the mesosphere.
• The Thermosphere and Ionosphere.
• The Exosphere.
• The Magnetosphere.

The ionosphere is the area that is traditionally thought of as providing the means by which long distance communications can be made. It has a major effect on what are normally thought of as the short wave bands, providing a means by which signals appear to be reflected back to earth from layers high above the ground.

The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.

Located within the thermosphere, the ionosphere is made of electrically charged gas particles (ionized). The ionosphere extends from 37 to 190 miles (60-300 km) above the earth’s surface.

The ionosphere is formed when energetic electromagnetic-and particle radiation from the sun and space ionize air molecules, creating plasma in the upper atmosphere. Irregular ionospheric layers are formed, which are associated with the northern light phenomena.

2. The ionosphere is where Earth’s atmosphere meets space. The ionosphere stretches roughly 50 to 400 miles above Earth’s surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth’s lower atmosphere — where we live and breathe — and the vacuum of space …

the ionosphere is important because it reflects and modifies radio waves used for communication and navigation.

The ionosphere regions can absorb or dampen radio signals, or they can bend radio waves, as well as reflecting the signals as described above. The specific behavior depends on both the frequency of the radio signal as well as the characteristics of the ionosphere region involved.

If you are speaking of furthest as to the radio waves being received by another station on Earth then short wave or HF, signals in the 3–30 MHz range can travel all around the Earth. The signal will bounce off the ionosphere and back to earth and continue doing this around the Earth.

The ionized part of the Earth’s atmosphere is known as the ionosphere. Ultraviolet light from the sun collides with atoms in this region knocking electrons loose. This is what gives the Ionosphere its name and it is the free electrons that cause the reflection and absorption of radio waves.

In the ionosphere, radiation from the sun is so powerful that it ionizes, or breaks electrons free from different atoms present in the atmosphere. Due to fluxes in solar radiation, temperatures in the ionosphere vary from 200 Kelvin (or -99 degrees Fahrenheit) to 500K (or 440 degrees Fahrenheit).

The thermosphere is directly above the mesosphere and below the exosphere. The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times.

Although the measured temperature is very hot, the thermosphere would actually feel very “cold” to us because the total energy of only a few air molecules residing there would not be enough to transfer any appreciable heat to our skin.

The particles in the exosphere are moving very quickly, so the temperature there is quite hot. Since the “air” is so thin in the exosphere – it is almost a vacuum – there are very, very few particles. We feel warmth when particles hit our skin and transfer heat energy to us.
