what is the relationship electronic configuration of element present i

1.	what is the relationship electronic configuration of element present in a group and period of modern periodic table
Answer» 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.

Answer»

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.
