Why is Yttrium in Period 5?
Let me ask you a question.
How many shells does yttrium have?
It’s 5. Right?
You have already seen the bohr model of yttrium atom in the above table.
From the Bohr model, it can be found that the number of orbits or shells in yttrium is 5. Hence, as yttrium has 5 orbits, it lies in period 5 of the Periodic table.
Why is Yttrium in the d block?
Before knowing this reason, first of all a simple question to you.
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 Yttrium is [Kr] 5s2 4d1.
So the last electron of Yttrium enters the d-subshell or d-orbital.
Hence, yttrium is the d-block element.
Is Yttrium a Transition Metal? Why?
Yes, Yttrium is a transition metal because it has incompletely filled d-orbital in its ground state.
Let me explain the exact meaning of this.
According to the definition of transition metals;
The element should compulsorily have incomplete d-orbitals, either in their ground state (M) or most common oxidation states (M1+, M2+, etc) then only they are called transition metals.
Now, the ground state of Yttrium means its normal state in which it has neither gained nor lost any electron/s.
So the ground state of Yttrium is Y.
And the ground state electronic configuration of Yttrium is [Kr] 5s2 4d1.
In this state, if we see the electron configuration of Yttrium, then it possesses incomplete d-orbitals.
Because, there is only one electron in the d-orbitals.
In order to have the complete d-orbitals, there must be 10 electrons in it.
But in the ground state electronic configuration of yttrium, you can see that it has only 1 electrons in d-orbitals.
Thus, Yttrium has incomplete d-orbitals.
And hence, as Yttrium has incomplete d-orbitals, it is considered as a transition metal.
7 Interesting facts about Yttrium
Interesting facts about yttrium element are mentioned below.
- The name Yttrium was derived from the name “Ytterby”, which is a small town in Sweden.
- Yttrium is the 28th most abundant element on the earth.
- The earth’s crust contains around 31 ppm of yttrium.
- Yttrium is a transition metal but it is also classified as a rare earth metal on a periodic table. Rare earth metals are not actually rare in quantity, but the fact is that they are spread evenly on the earth and it is very difficult to find these elements at one place on the earth. Thus they are rare in the context of available resources.
- Out of all the rare earth metals on periodic table, yttrium was discovered first.
- In the entire world, the yttrium element is majorly produced from countries like China, Russia, India, Malaysia and Australia.
- Yttrium is not found as a pure element from the earth crust.
