Question

predict the group and period in which the elements belongs whose atomic number is 23​

Answer 1

5th Group and 4th period and block d

Answer 2

Answer:

To find the period in which the element belongs, we must write down the electronic configuration of the element

Electronic configuration of 23 :

2,8,8,5

There are 4 shells, so it belongs to period 4 (Period number indicates Number of shells of an atom)

The valence number of electrons indicates the group to which the element belongs.

Here, the number of valence electrons is 5 so it belongs to group 5

Group 5

Period 4

So it's a transition element
