The atom numbers the the as yet undiscovered next two members the the collection are 118 and also 168.
You are watching: Find the atomic numbers of the as yet undiscovered next two members of the series.
The noble gases is a team of chemical facets with comparable properties such as under standard problems they room all odorless, colorless, monatomic gases with very low chemistry reactivity.
The heaviest recognized noble gas metal is radon, atomic number 86. Whereby The outermost covering configuration that radon is
Electronic construction of the following noble gas is:
Therefore, atomic variety of the noble gas after Rn is 86+32 = 118
The atomic number is the variety of protons uncovered in the cell core of every atom of the element.
Electronic construction of quiet the following noble gas have the right to be derived by adding
So the atomic number = 118 + 50 = 168
Therefore the atomic numbers that the together yet undiscovered following two members the the series are 118 and 168.

Yuri Oganessian has already discovered the following noble gas in ~ atomic weight 118, (which is 86 add to 32). The next most likely, if ever encountered, need to be 150 (which is 118 to add 32) or at 168 (which is 118 plus 32 add to 16).
