Is Element 118 a noble gas?
Also, why is Oganesson not a noble gas?
According to the periodic trends, Oganesson should be a noble gas. However, due to relativistic effects, Oganesson is predicted to be a solid at room temperature. However, Oganesson is predicted to be 'not so noble' because of 1 its location on the periodic table and 2 due to relativistic effects.
One may also ask, why is element 118 so expensive? The most expensive natural element is francium, but it decays so quickly it can't be collected to be sold. If you could buy it, you'd pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium. Atoms of synthetic elements cost millions of dollars to produce.
Also know, what is 118 on the periodic table?
Oganesson is a synthetic chemical element with the symbol Og and atomic number 118.
