Why is Nobelium in Period 7?
Let me ask you a question.
How many shells does nobelium have?
It’s 7. Right?
You have already seen the bohr model of nobelium atom in the above table.
From the Bohr model, it can be found that the number of orbits or shells in nobelium is 7. Hence, as nobelium has 7 orbits, it lies in period 7 of the Periodic table.
Why is Nobelium in f-block?
Before knowing this reason, first of all I want to ask you a simple question.
How can you determine the blocks-wise position of elements?
The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.
For example; the electron configuration of nobelium is [Rn] 5f14 7s2.
So the last electron of nobelium enters the f-subshell or f-orbital.
Hence, nobelium is the f-block element.
