Question

in terms of period group and block locate the position of element having z = 121​

Answer 1

Answer:

Period:8, Group-3rd, Block-F

Explanation:

According to Aufbau's principle the EC of z=121 will be [Uuo] 8s2 6f1

Therefore period will be 8 because 8 is the largest quantum no. in EC. All f block elements lie in group 3 because f block elements are either lanthanoids or actinoides. Block will be f because last electron goes in 6f subshell. This element will come under transition metals. The name of this element will be Unbiunium[Ubu].Hope this helps you.
