Explanation:
The element with 30 electron is Zn (Zinc)
The find Block the last of electromic configurate subshell i.e D which is the block of this element.
The highest stoichiometry decides the period of that element which is 3 so the period of this element is 3.
The group will be decided by block and so the block is d then 2 + power of last subshell in that electronic configuration will decide its period
10 + 2 = 12
The element belongs to 12th Period.
