How high of atomic number to get g-block electrons?

In summary, the recent discovery of Element 118, Og, has allowed for a more organized Periodic Table. However, the addition of Element 121 may create a new g-block section, similar to the f-block for the rare Earth's. It is uncertain if this will happen as there are potential complications. More information can be found in this Wikipedia article.

I have just read that Element 118, Og, has been discovered, which it would seem will allow for a nice, neat Periodic Table again, last seen when Lw (103) was added (although that should be in Group III, but whatever, it was a nice, neat table). It seems to me that once Element 121 gets discovered, there will finally be an atom that has a g-block electron. Is this accurate? Will the Periodic Table have to start a new g-block section in a similar way that the rare Earth's represented the f-block?

We don't know. It's a natural extrapolation, but there appear to be plenty of complexities that could spoil it. This Wikipedia article provides a decent overview:

I would expect the current calculations on the first g block elements to be quite accurate.
 

1. How do you determine the highest atomic number for g-block electrons?

The highest atomic number for g-block electrons can be determined by looking at the periodic table. The g-block refers to the elements in group 3 to group 12, also known as the d-block. The highest atomic number for g-block electrons would be element 118, Oganesson, which is currently the heaviest element known.

2. Why are g-block electrons important?

G-block elements have unique electronic configurations and properties, making them important in various chemical reactions and applications. They also play a significant role in the transition of elements from metals to nonmetals.

3. Can elements with higher atomic numbers have g-block electrons?

Yes, as mentioned earlier, the g-block elements include elements in group 3 to group 12. This means that elements with atomic numbers higher than 118, such as 119, 120, and so on, can also have g-block electrons.

4. How are g-block electrons different from other electrons?

G-block electrons are different from other electrons because they are located in the d-block of the periodic table, which has unique properties and characteristics compared to other blocks. G-block electrons also have higher energy levels and different orbital shapes than other electrons.

5. Can g-block electrons exist in isolation?

No, g-block electrons cannot exist in isolation because they are a part of an atom. They are located in the outermost energy level of an atom and are involved in chemical bonding and reactions with other elements. However, scientists have been able to isolate g-block elements in a laboratory setting for research purposes.
