Noble gases are gases in the far right side of the periodic table. These He (helium), ne (neon ), Ar (argon), Kr krypton), Xe (Xenon ) Rn (radon ). He's outside, in the air are gases inert gas inert gas with electrons in the outer energy levels of atoms.. it is packed full. Except for helium, and 8 electrons in the last orbit include the others.There are 2 electrons in the helium.
More than eight electrons in the outermost orbit of an atom are to be found. So noble gases, electron flow normally they don't. So, they are unable to create a composite. However, in the upcoming time, the inert gas could, it was observed that compound. Noble gases “inert gases” or “inert gas” is known as. Insert means that the reaction does not give. Noble gases was not known until 1894.
Then as a result of research and experiments, neon, krypton and Xenon gases were discovered.In 1900, also by the decay of Radium radon gas, new elements are added to the list. Noble gases, except helium and radon can be obtained commercially by distillation of liquid air. helium is extracted from natural gas. The forces between inert gas atoms is almost negligible. Is dominated by weak van der Waals forces between the atoms. Noble gases are nearly ideal gases under standard conditions. Therefore, the melting and boiling points are very low. Noble gases diatomic gases are single. Noble gases they are determined.
Noble gases colorless, odorless, tasteless and non-flammable. .In recent years, studies of noble gases can form compounds. Heavy noble gases such as Radon can be removed from the outermost electrons. Only a few hundred noble gas compounds have been formed. The requests of the noble gases entering into the reaction as follows: can be listed. What > He > Ar > Kr > Xe > Rn .
Florina a compound of xef2, inert gas is used as the agent the moment that are available in the market. Helium; the world's most abundant element after hydrogen in the universe. Which are a large part of the helium the universe, nukleosentez were formed during the Big Bang. The business And the amount of helium is steadily increasing. There are plenty in the sun. Take a look at the princess inert gas; argon, Xenon, an inert gas, while the most expensive is the cheapest. Noble gases are very often used in lighting. Noble gases used in the excimer laser also. Some noble gases used in medicine. For example, helium, sometimes facilitating an asthma patient of the respiration is used.
From top to bottom in the periodic table atomic number the atomic numbers of the noble gases in a way that will increase are as follows:
He (2), (10), R (18), Kr (36) ,Xe (54), Rn (86)
Helium balloons flying away.It is lighter than air and hence the balloon rises into the sky
