Incomplete period in periodic table
WebWell, that's an incomplete d subshell, because I can fit a total of 10 into my d orbitals. And so iron would be an example of an element whose atom has an incomplete d subshell. So iron is a transition metal. Let's write the electron configuration for zinc. So let's find zinc over here, so right there on pour periodic table. WebAnswer (1 of 4): Hypothetically, the number of elements in the 6th period and the 7th period should be the same. But the later elements belonging to the 7th period are highly unstable.
