WebJun 6, 2024 · The Group 18 (once known as group VIII) elements are essentially chemically inert (light blue column on the right). All these elements exist as monatomic gases at room temperature.If we look at the electron configurations, we see that helium (atomic number 2) has a full shell of two s electrons. Since there are no electrons shielding this shell from … WebJun 8, 2024 · Though Helium has 2 valence electrons and not the usual Octet-8 electrons, it is still considered a Noble Gas. This is because Noble Gases all have a stable and complete configuration among all their elements. So, for example, though Helium has 2 electrons, it is one of the most stable elements. Also, it has 2 energy levels.

WebLet's start with the prior that in a hydrogen atom the principle quantum number determines the energy - so maybe full shells correspond to noble gases. Now, I understand that in helium the n=1 level is full, so it is a noble gas. Then, beryllium has a full 2s subshell, but empty 2p, so it is a metal. Neon has the n=2 level full, and is a noble gas. flushing heating core

WebThe atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take … WebThe noble gas elements do not react with other elements as they are less electronegative and unable to attract the lone pair of electrons from noble elements. Some of the examples of noble gas compounds are XeF2 , XeF4 , XeF6 , XeO3 , XeOF2 etc. Due to this, the noble gases form compounds with fluorine and oxygen only.

WebSep 15, 2010 · The Noble Gases are the most stable because they have a full octet *and* a net charge of 0. So they're basically willing to take on a charge if it means they can have a full octet, because of how it brings them to that sort of equilibrium. Of course, the transition metals get more complicated because of their d-orbitals and f-orbitals, but that ...
