The atomic number of argon is 18. Will argon tend to form bonds with other elements?
Argon is one of the noble gases (group 18) and thus does not normally combine with other elements. Elements follow what is commonly termed the "8 is great rule". What this means is elements will try to obtain 8 electrons in their outer energy level (called valence electrons).
Argon being number 18 has the configuration 1s2 2s2 2p6 3s2 3p6 which is a full outer energy level. The 3s2 combined with the 3p6 is an octet (8 electrons) so argon does not need to go looking for other electrons.
Argon is still studied based on kinetic theory of gases, also. Ramsey noted that the gas is monatomic and therefore found not to be a body composed.
This discovery of a gas in air is a resounding success in the scientific circles of the time. But far from being a finished task, success was likely to stimulate further research that will finally bring the discovery of a family of rare gases.
Studying its characteristics, it was discovered that argon is not totally inert, photolysis of hydrogen fluoride in a solid argon matrix at 7.5 kelvin, produces argon fluorohydride, HArF.
Because of its lack of reactivity, argon ensures an unreactive atmosphere, therefore it is used in light bulbs, with the aim of filament protection.
We can find argon in medical devices which are using laser technique and in semi-conductors industry.
There are several ways for obtaining argon, other than naturally:by catallitic burning , from liquefied air, using fractional distillation.
Argon is an element with the atomic number 18, which means that is has 18 protons and 18 electrons . The K shell is complete with 2 electrons, the L shell is complete with 8 electrons, and the outer shell, or the valence shell, is also complete with 8 electrons.Thus all the shells are filled with fully required number of electrons and so it is stable in its electronic configuration.The electronic configuration of Argon atom is: 1s2, 2s2, 2p6, 3s2, 3p6.Having a very stable electronic configuration,under normal conditions,it doesnot chemically combine with any other elementsto attain a more stable configuration. Argon thus does not tend to form bonds with any other elements. However, researchers have been able to create stable compounds of Argon with Fluorine and hydrogen .
