what is the relationship electronic configuration of element present in a group and period of modern periodic table
Answers
Answer:
Electronic configuration express about the arrangement of electrons in an atom. So we can calculate the Group no. and Period no.
Explanation:
Maximum principal number express about the outer shell which is equal to the period number. If period change means orbit change.
For Group no.
If last electron enters in S orbital then the no of electrons in s orbital is the group number
If last electron enters into d orbital then group number is equal to the number of electrons added by 2.
If last electron enters into p orbital then group number is equal to number of electrons in p orbital added by 12.
all f block elements are in 3rd group.
